Hi
the game has natural deviations programmed in. no club is 100% precise. what actually happens is a circle of precision. I don't know the exact #'s but for example:
if you hit 10 identical shots from 200 yards in identical wind with the most precise iron in the game, you still are likely to have 10ft circle, which means 1 shot can be 10ft left and other 10ft right, and others short or long and anything ini between. sometimes it will be inside 1ft... then there could be deviations...
this example is simplistic but it should illustrate some things
