I am not sure how the handicap number is assigned or calculated, but the better your official average the lower the number. If there is a handicap prize in addition to the class and concurant, your score and handicap number are added. To win a handicap one needs to have a fairly good score and shoot quite a bit above your average.
We don't use the handicap system much, and I think Doug has the calculation. send me a pm and i will get it to you as soon as i get it. I think i know, but hate being wrong.
