Although Kirian said he would cap the number of players at 128 and we're well past 64 sign-ups so we're pretty much confirmed for 7 rounds/weeks.
Yes; we currently have 102 signups, so definitely 7 weeks.
BTW, any specific reason to cap signups on 128? I know that with more we can have more than one player win all matches if 7 rounds are played, but with a cutoff to top 16 and single elimination round I don't think this causes any problem.
I actually considered 100, and entirely because of calculation time. In fact, I'm likely to try to hire* an assistant this time around just to double-check me, as I made several mistakes in scoring last season (none of which should have contributed to standings). Unfortunately, Challonge can't handle things like requested byes and the like, doesn't handle dropouts well, and obviously can't figure out to pair sets with no sets. If I had more time, I'd try to write something for myself...
...or perhaps not, but I don't actually have the time to write such an app yet anyway. Perhaps someday, when I have time, I can write a challenger to Challonge, but that's... a while in the future.
*And by hire, I mean request a volunteer to work for tips.
