You know, I have noticed a quiet a few times that sometimes when you have to reach a certain distance that you never exactly get that distance, sometimes it is not even close (not counting head wind)
Lets say the hole is 130 yards away and you get a club rated at exactly 130 yards, this is not assuming strong tail or head wind. I noticed a lot of times it won't make it unless you go a club up, I am just curious as to why this is the case.
