Honestly, I'm not real sure Jeff. That is my mistake; I must have forgot I invited you to 20B and so forgot to click your name on the team tournaments. My apologies.
Flyingbender, you didn't get downgraded because of your teammates being booted. The 1v1's are where the majority of 20 points come from.
https://docs.google.com/spreadsheets/d/1dgrUIKbGmrp44X-HwphmmMDzQqbbFbq5xqlAVr5tm2k/edit?pli=1#gid=0 is the spreadhseet with the statistics. The top 50% of 20A (top 8) were guaranteed a spot in 20A again. You needed at least two more wins to be in the top 50%. You did very well in the 2v2 tournament, so I don't think boots are a problem there. In 3v3, boots may have made a difference. But even assuming your teammates were active, you would have needed to be at least 3-2, possibly better to guarantee a spot in 20A this season. Your 1v1's were your weak point. The top 4 in Group B (top 25%) were promoted. After that, the rest of the players in 20A were voted on (your name was in the voting, you just didn't quite get enough votes this season). If you finish in the top 25% of Group B this season, you will be promoted back to 20A, and if you have a poor season, you may get in by vote.
