One of these days I will see if I can find an elegant simplification without side effects.

Chris' is just DX A minus DX D, and an easily learned pattern or memorized table. You can think of it as division but it's just halving.


With a recorded MOD that is half DX -10 (and not using that optional rule where you have to think about whether each DX is odd or even), it means that half the adjDX values seem rather inefficient because you get a -1 to be hit with every other DX increase.
