Note #1: Don't recommend backfilling the 32 in the final 128

Before this one, the first 16k endgames ended up being a 2 gamble because I wanted to backfill the 32 only to get a 4 and lost a 45/55. This endgame ended up nearly perfect. I don't think it's work risking a roughly 1.5-3% chance of a having everything in scrambles.

What does “backfilling the 32” even mean?
