That's strange. In group C Ronnie wound up 9th 3 out of 4 times. 
Looks like that happened a lot. How about doing some calculation to determine the probability that a guy could get the same number 3 out of 4 times. Remember the (n-r)! stuff?
Many people think that the guy who put the random number generator in the tabulation program is either too stupid or too dishonest to do it fairly. If I were in charge of stunt at the Nats, I'd have people draw numbered pingpong balls from a bag for flight orders. Guys who think the virus is a hoax could lick their balls.
Betty Adamisin came up with what I think is a better way to assign flight orders: draw the first round randomly and map the other three rounds from the first round by a method that distributes the flight orders more uniformly. We do that for the Nats Open finals. The sum of a guy's flight orders for the three rounds is nine.
