Bike fitting - should I follow the instructions ?

    Please see: http://www.focus-bikes.com/int/en/bikes/bikes-2011/category/racing-bikes-3/model/izalco-pro-10-4.html

    I went to cycle superstore in 2008 to have a bike fitting (they are using bikefitting.com). As a result I got following measurements (unfortunately I have no camera or scanner to upload an image of the printout).

    Following the focus chart my measurements look like this (F: - is the value for the frame sized 62):

    A - 635 (F: 620)
    B - 611 (F: 588)
    C - 72,5 (F: 73,5)
    D - 73,5 (F: 73)
    E - 400 (F: 405)
    I - 45 (F: 43)
    J - 1048 (F: 1005)

    My question here is: there are some differences especially between A,B,J and will they or do they make any difference here (if I was to get the focus frame?).
    I have another printout including positioning of saddle, height, stem length etc. Will I be able to compensate the differences with bigger/smaller stem etc.

    Or should I just feel the bike and not really bother with those printouts ?

    B (horiz TT length) and G (headtube length) are the most important.

    Did your bikefit really recommend a 61cm toptube? That's completely off the scale. You must be about 7 feet tall.

    I have no idea what things like chainstay length are doing in a bike fit.

    I think the guy that was taking measurements mentioned some brand of the bikes they are selling. Maybe it was Giant.

    Anyway im 195 cm tall - that's I think around 6'4" or so. I had 58 frame before and it felt kind of small + gave me some neck pains so I couldn't raise the seatpost high enouf + had to have 1 certain position of the saddle otherwise pains in the neck happen after 10-15min cycling. So I decided to get bike fitting before I bought focus which was closest to the results of the fitting, eventhough the bars and stem that came with it were too big.
