    You're bladdering on about your op again I see, bookies make money! Unreal, we all know that.

    Again it is a theoretical application of a concept I believe to be fundamental

    A concept you claim to understand but have not appeared to on this thread

    A concept you claim I am "struggling" with yet despite repeated calls cannot point me to my posts where there is "evidence" of my "struggle"

    RJ, did you or did you not state, and I quote:

    Any post relying on the law of large numbers can be disregarded as its not relevant to selective punting

    If you did say this it is proof you haven't a clue what you are on about

    If you did say this it is proof you haven't a clue what you are on about

    I did indeed, as I consider a number in the range of 750 small out of a pool of over 500k, the selective punter selects this small number of events, the bookies have them priced consistently, some of them are bad value, some are good and some are about right in bookies terms.

    Your insistance that the law of large numbers can be applied to a small finite number of non routine selections is nothing short of ludicrous, its not throws of the dice old boy.

    You can apply your theory to roulette spins etc if the wheel isn't biased, you can't apply it to everyone's punting habits no matter how much you'd like to.

    Your inherent problem is that you apply the fluke or luck label or the value label to all positive ROI from a sample regardless of its size, that's an inherent conceptual flaw that you can't overcome in your own head.

    Its born out of an inability to pick winners yourself, regardless of value imo, you than speel out the value muck as you have nothing else to contribute.

    If I don't have a clue how did I from a 190 euro betting bank lay over 1000 horses on betfair and now have over 1500? What are the chances of that happening if I don't have a clue?


  • Closed Accounts Posts: 7,669 ✭✭✭Colonel Sanders


    RJ we have went through this before on this very thread. In which you:

    1. Stated I was "struggling" with these concepts yet could not point me to any post where this was apparent
    2. You posted a load of rubbish such as the quote above that suggested you don't actually understand the theory of what I am discussing (you've backed this up in your last 2 posts)
    3. More than once you've told me I said something I did not
    4. Not once when called to point to these posts where I allegedly said these things could you actually do so

    If you like re-read what we spend several pages discussing again. I'm not posting the same thing all over again


  • Posts: 23,339 ✭✭✭✭ [Deleted User]


    ............
    3. More than once you've told me I said something I did not
    ...........

    Nothing short of a lie, hardly my fault you can't comprehend ;)

    I think it is yourself who posted that "you seem to be saying" when I was saying nothing of the sort, the problem being your comprehension :)

    Regarding rubbish, your application of the law of large numbers to selective punting is nothing short of rubbish.

    What's amusing is that even though you have a pure maths degree you can't apply what you've learned (or learned off ;) ) appropriately :)

    From your posts here I think you'd struggle with honours maths for the leaving cert.

    Please do answer how I have turned €190 into €1500 since August by laying short priced horses (1000+) on Betfair if I don't have a clue :)

    While I do that you wait for PP once a week enhancements so you can practise what you preach, ie knowing nothing about your selections :)

    Q.E.D as the maths numpties say, Q.E.D. :pac:

    FWIW I've been accused by at least 3 posters of attributing their successful punting to "luck". This is not what I stated if they bothered to read (and understand) what I posted they'd see this. I'll not respond to any further posts on this topic as I've repeated myself at least 3 times

    Secondly I'll not reply to any further posts that call my ideas "wrong", "flawed", "inept" or suggest I'm "struggling" based on posts along the lines of "look at my (finite) betting history & I don't care about value". Again I've replied to this repeatedly

    A very decent thread and the OP is on the ball. In my opinion the bookies prices on each horse running are typically 15% less than what would be required for a consistent level stakes punter to break even longterm.

    Few things, I'll point out for you
    - as you reckoned the 2012 Gold Cup was a two horse race your knowledge of punting is very weak
    - as you reckoned both Long Run and KS both should have been shorter your knowledge of value is non existent as the bookies won't be giving much value on the market leaders in the Gold Cup
    - €1500 - €190 is not €1200
    - I don't lay horses every day so your 9 a day estimate is way out
    - I'm no expert but am 100% confident neither yourself
    Colonel Sanders or RichieLawlor have the ability, intellect or knowledge of racing, punting or value to do what I've done.

    - your buddy reckons 750 is a large number, my number of bets is far in excess of that, to do what I've done says something that the three of ye won't like.
    - Maths boy would like to put it down as luck or a fluke, it can't be value as he reckons I have no clue about that.

    We can't place an infinite number of bets, the smaller the number the less the results can be explained by the law of large numbers.

    750 horse racing bets is a small number.

    I make all of my betfair profit due to value so I am not at all struggling with the understanding of anything you have posted, you are struggling with the application of your degree, as you've said you are pedantic.

    Why are you repeatedly using the notional figure of 750 to discredit the OP when in fact you place a number of bets far in excess of that?


  • Closed Accounts Posts: 7,669 ✭✭✭Colonel Sanders



    Concept 3: The Law Of Large Numbers

    The law of large numbers says, in lay mans terms, that the larger the number of "good" bets we place the closer and closer our profit on turnover will get to our EV (5% in the coin toss example)

    You should also reference this part of my "on the ball" OP if you are about to post about "luck" and what you believe I have said about it (but not been able to quote)

    750 bets over 50 years - selective punting.
    I don't practise selective punting, I lay horses I reckon are underpriced on betfair. The number of bets I place would be a large number over 12 months.

    Have edited below to include other factors that influence p:

    What the hell, for the last time (and I mean last time):

    A +ive RoI is due to one of 2 mutually exclusive things:

    1. The gambler has placed a series of bets where the weighted EV is +ive
    2. The gambler has placed a series of bets where the weighted EV is -ive, but variance has been kind

    I will call the person "lucky" if 2 is the case. If p is the probability of 1, 1-p is the probability of 2

    If you show me a +ive RoI based on 10 bets I am not very confident whether its down to 1 or 2 so I might estimate p to be in the region of 0.5

    If you show me a +ive RoI over 1,000 bets I will be more confident 1 is the case (confident bit not certain). I will assign a value in excess of 0.5 to p but a value less than 1.

    If you show me a +ive RoI over 10,000,000 bets I will be even more confident 1 is the case and would assign a value to p that would be very close to 1 (but not equal 1)

    This is how the law of large numbers is relevant to finite samples of bets.

    In the limiting case where we have an infinite sample p=1 (and hence the probability of option 2 is 1-p = 0) i.e. you cannot win in the long run unless your weighted EV is +ive

    EDIT: the above is the case where we only know:
    1. Whether RoI is positive (not the size of it)
    2. The numbers of bets

    There would be other influences on p also

    eg the size of the RoI and actual turnover. Perversely the conditional expectation of a -EV punter given he's shown a +ive RoI over the short term can actually be quite high depending on the average price they're taking

    Markets they're betting on. If the RoI is based on roulette p is close to zero (can't say zero as they may be in cahoots with a casino worker)

    Staking. If they're betting fivers and showing a huge loss after 9,999 bets then bets an even 10k to show a profit after 10,000 that would influence p

    etc etc etc

    There are any number of factors you could consider (given the information is available) to influence your estimate of p

    Not at all, I'd haveno interest in reading references not applicable to small sample sizes made up of what are essentially outliers.
    Seems as you have no clue about the application of the law of large numbers I'd suspect your latest reference point is equally misunderstood by yourself.

    A pure maths degree, you're some add for it.

    Best of luck with the paddy power enhancements, when that hits a losing run thetes always GA :)

    Because one race had an odd result I have no knowledge. There's a good sample size for you eh.

    How do you know what's value or not, the bookies have every Gold Cup favourite priced spot on do they.

    Wow you're really scraping the barrell with the subtraction jibe.

    It's an average of 1000 divided by roughly the amount of days you said you started, hope this helps.

    The fact you think there have been 1000 wrongly priced favourites in that time yet the GC favs are priced spot on is laughable by the way.

    What have you done, turned 190 into 1500, exactly how amazing do you think is is. Also I have no proof you have done this.

    Sorry, any post other than op with more than eight lines is too much of an effort.

    Put simply, bookies make money in a 50-50 coinflip by offering both outcomes at 5/6 or similar odds against. If a punter were to back 50-50 chances at anything over evens like 6/5 then the punter would eventually win.

    Alternatives to what the OP deemed a "fundamental" were rejected as the OP stated he could not accept something as "fundamental" that did not stand up to rigour.

    Others may well (in fact the OP wished them well if they wanted to), but the OP finds such a stance irrational

    Yes I am serious, do you even know what you are on about?

    If you are saying 15% was the probability of either or both winning you are bang wrong. If you are saying 15% as in the bookie had an over round of 115% I would be surprised if it was that low, its normally around 130%, I will check it out when I get home.

    Rich coming from a guy who doesnt have a rashers about maths and has to follow other posters to have winners.
