How do Tournaments Work?

Yes, Q=1 in sep 2014, maybe it has changed. Also I think they round it to the “ceiling”, i.e. (19 + 7 x 1) / 5 = 5.2 means 6 rounds. Let’s see if one OGS developer clarifies it.

Well, looks like that tournament ended up with 7 rounds.

I have a guess at the real answer here:

How many rounds in a tournament?

I looked around some more and the tournaments I can find seem to be consistent with the formula floor((P+2*7)/5) limited to a maximum of 8 rounds. P=4, 3 rounds (posted before) P=11, 5 rounds P=20, 6 rounds P=21, 7 rounds P=29, 8 rounds P=36, 8 rounds (maybe 8 is the max?) This formula predicts that P=21 would be the first tournament with 7 rounds, and P=26 would be where they reach the max of 8 rounds. EDIT: found one with P=21, and it worked! (From a three-year-old question here.)
