This player was DQ'd despite having a losing record, but I've see this happen before with a 1-3 record and another with a 2-4 record. What is unique about this new one is it was in just 3 matches with a 1-2 record. So there is no guessing as to which matches were strikes!
So how can a player go 1-2 and get DQ'd?
Using my Estimated Dynamic NTRP Ratings, here is the player's chart.
The chart shows the self-rated 4.0 had ratings well into the 4.5 range for each match, each being a strike. So my ratings agree with/correctly predict the strikes and DQ yet again.
The player played doubles the first two matches losing both but by close scores. That alone isn't going to generate a strike though, otherwise a lot more self-rated players would get strikes. What caused these matches to be rated so high is that the opponents were high rated 4.0s, but more importantly the partner was a pretty low rated 4.0. This is a recipe for a strike as the computer looks at the ratings of the players involved and figures the self-rate has to be really good to have carried a low rated partner to such a close loss against strong opponents.
Then the third match was a lopsided singles win that was high rated and would seem to confirm that the self-rate really was that good and carried the partner in the doubles losses.
So yes, it is possible to get strikes and be DQ'd with a losing record in just 3 matches.
If you are aware of any other strange or unexpected DQ's, let me know.
