If you look at this photo showing the risers, spacing is less than 12" on average between the top plates of the risers. I just finished securing all of those and started gluing the foamboard to the ply. I beleive if there is any additional warpage, which I doubt considering it has been in this climate for months, the foamboard on top will mask any of it.
To me, 3/4" is overkill (this is N scale BTW), 1/2" might of been a better choice.
Birch plywood probably would of been the better choice )if 3/8 or 1/2" was available), or that 'stuff' I hate; flakeboard/OSB (at a much cheaper cost). I didn't choose 'finished grade' ply since I wasn't making furniture and no one will see any of it.
