Nobody does shoot all their rounds in the 50's.
When you look at someones stats, that is only part of the story.
Take 'Ready-Go's" for example. Many players if they are not shooting well will simply withdraw because it is a waste of time for them at that point.
Same thing with tournaments. If it is an unlimited and you have already shot a 63, why would you finish a round that would end up higher than that? Again a waste of time for these guys.
No matter how you try and spin it, this thread started as a cheater thread.
Any time you do that you are going to have other players taking offense.
Telling players to prove to you that they are not cheating isn't going to go over either.
Happy hitting
