I haven't yet changed the bucket function back to modulo from the base2 sizing and bit mask (vs. mod) truncation. So I can't yet offset any of the the head size increase with an increase in load factor. So it will go from 8 to 16 GiB, which is 4 GiB more than I simulated with. This won't affect the maxi though, and I'll soon have a measure of actual point table search reduction.
