Also it's unlikely that you will have like 8 pawns on 6th rank, yes
even on 5th or 4th rank having 8 pawns there from one side is nonsense.

Loads of things are nonsense.

Like having a king on the other side of the board with both sides
having all pieces still left, that's also nonsense.

Loads of those limitations make it go like 10^40 easily at most.

I can remember in ICCA some mathematician came down to 10^43.
