The guy in question self-rated as a 3.5 in 2009. Played many matches in 2009 in 7.0 and 8.0 mixed; never played spring adult season. Computer moved him up for 2010 to 4.0. He then played two matches in the winter mixed season, both with computer-rated 3.5 partners. The computer DQ'd him and moved him to 4.5. I cannot figure this out. Since he played with 3.5 partners, he was OK to play 8.0 mixed with these 3.5 partners even if he had been a 4.5 all along. So why would he be DQ'd?
