White's 6-1 5-1 4-1 and 3-1 take two checkers off, right? So if Blue has played bar/16 he has aces to hit and the 6/36 numbers you counted for 65 64 63 54 53 43 to get his last two checkers out of White's home board. If bar/19 23/20, aces to hit and the 4 good doublets you counted to spring three checkers out.

How 2-X plays seems not very important since, if White has rolled 1-X (other than 2-1 and 1-1), he's going to bear off next roll unless he rolls 2-1 or Blue hits first.

White's 2-1 plays 3/1/off after bar/16 -- Blue has 6 immediate BG savers, and needs 10 pips and 2 crossovers. After bar/19 23/20, 2-1 plays 3/2* 3/1 -- Blue has zero one-roll BG savers, and needs 10 pips and 4 crossovers.

Similarly for 2-1 if White rolls 1-1 bar/16 is better -- 6 vs. 0 one-roll BG savers, 2 crossovers vs. 4, and White needs to bear off his last two checkers from the 3 point instead of the 2 point.
