Is it possible that the 1000 rated player is often in reality a 1500 level
player BECAUSE he is in the US Amateur event? Think about it. You have a limit
on the total rating for a team, so you place 3 masters and a class C who hasn't
played a rated game in a year on the same team. The masters work with the "class
E" for several months to make him class C (or even class B) and that player then
beats a class B or low class A player. Not really that impressive of a result.

To verify this, check the rating of the upset prize winners (within a year of
winning the prize) for the past 4 or 5 years and let me know the result.

Also, you hear of the one or two upsets a year where a player 700 points or more
beats someone, but what of the thousands of games played where this does not
happen?
