I was thinking about it, but there are other contenders for interesting 
subsets of proof games: mirror-symmetric, checkmate, castling, en-passant, 
promotion, Pronkin, Ceriani-Frolkin, ...

And there's the question of whether it is PGs or SPGs which should be 
counted.

But in the at-home case, 14 plies is exceptionally far, and I'm very 
confident in the results. So I sent the at-home PG sequence and it got 
accepted!

Someday I plan to extend the general PG sequence A090051 to ply 9, and I 
think that this one will deserve its SPG version to be sent to the 
encyclopedia as well.
