How the balancing works
We sort participants by rating, then snake-draft them across the chosen number of teams (1 โ 2 โ 3 โ 3 โ 2 โ 1 โ 1 โ 2โฆ). Snake-drafting is provably optimal for small groups and minimises the gap between team totals. If two ratings are tied, the tool randomises their order so the result is not always the same. Re-roll for variations.
