In the demo currently.
Most will cap at 750. Usually a 100-150cm gap between sizes.
This threshold will increase in the coming update. Mainly cause it was happening too quick, so easy to miss CG's
it happens with the full game too it seems I'm at 15/16 for one of the protagonist and like 1100+ size with no clue what size I'm missing (using wager if that matters).
I would most likely guess it's the smaller sizes, since it's super easy to breeze by those.
