Jimbog1964: I am now at a level where I can see how better player's can shoot lower than me regularly. Whether I can ever do that is another matter, but I can see how shooting well in to the 50"s does not require cheating.
One thing to keep in mind, no one does it consistently...check the RG leader boards down at the bottom and look at the WD's.
Also, take note of the single play weekly tourneys, many times the best players do not have a score posted, this usually means they WD'ed.
