Thanks for that. I understand much better now. Naccel is a bearoff to the 6 point. That's why you must convert to a traditional pipcount by adding 90: you are moving 15 chequers 6 pips to bear them off.

In this instance, you trying to bear off White's chequers backward to the 6 point, which takes 12 pips, so the Naccel count is -2(0) or 0(-12). The chequer on S0 is already borne off, so counts for zero pips, but is still part of the formation.

I've drawn the same structure as a traditional bearoff for Blue in the diagram below. The pipcount is 12 no matter how many chequers are already borne off (pipcount = 0), so you can use any of them you like if it helps in visualising the chequers still on the board.
