Thanks for the praise I think that was by far the best set of 12 I've managed
It was a recurve (30lb) olympic archery kit from merlin in UK, got one for the OH as surprise for Christmas, and then she got me one when it I took a liking to it.
As I said I've managed to get to the maidencity archery club in Derry twice now, - every second Saturday morning - they've put the nock point in the correct position, and pointed out a few basic issues I had. I'll most likely join the club for 6 months to see how I go over the summer; but in that time I'll only get there max 12 times so I'll need the weather to be kind to get some practice in.
Look at the videos on how to tune a olympic recurve.
Stuff like (as you already got fixed) the knocking point, brace height, tiller, correct release, correct anchor point, correctly holding the bow etc etc.
There are a million and one tiny things that you can do that will have a tiny impact on your shot, but all combined it creates consistency and accuracy.
Also be patient. When you try something new which is supposed to improve your performance , your shot will always get worse before it gets better. It takes a while to get used to a new element in your shot.
I changed the way i held the string in my finger tab last night. Spent hours with terrible shooting before it finally clicked and my shot went back to the way it was before. I changed the way i held the string because i was getting a numb middle finger, so i distributed more of the weight onto the first and third finger.
