Hi Nicolas,
12.0 moves seems to be quite short to get the stalemate task without the e.p. trick.
We could manage both records (with and without e.p.) after you publish your PG.

that the f pawn has to be eliminated as pointed out by Andrew so it seems to be hard
to improve the 6.5 moves. Perhaps this idea will function with the non-e.p. case.
Is your PG dual free?
