I was at the legg mason tourney and they had one of those small tents w/ a radar gun. I'm curious how accurate these things are, cause this kid (like 14) went before me, served in the 60/70 range, then a few people went, then myself, the best i could do was low 90's. The kid then says to his dad, that he thinks that if you hit the ball toward the gun, it seems like those readings are artifically higher than otherwise. He goes back in, and aims right toward the gun, and all of a sudden he is hitting the low 90's, and clearly not hitting any harder then he did before. So are those radar guns meaningless, or was it just the setup here.
