>>57050363>Table Mountain has 30 floors in total, putting it at just under 7% of the game's total floor count.1 / 0,07 = 14,28571428571429
14,28571428571429 * 30 = 428 floors rounded up
I don't know where this math is from but:
Table mountain + Tainted path = 99F (Table mountain has 30F has you said, Tainted path is a direct continuation since it starts at 31F)
Ceremonial Cave has 30F
Ravine of the dead has 50F
Kitchen God, Scroll cave and Final puzzle have 99F (granted Both Kitchen God and Scroll 99F versions are totally optional)
So that's 99F x 4 + 30F +50F = 476F
Regarding PMD exact numbers
Beach = 4F (+ bottom)
Bluff = 7F
Mt. Bristle = 9F (+ summit)
Waterfall = 9F
Apple = 12F (+ interior)
Coast = 9F (+ 5F from Small Path)
Mt. Horn = 14F (+ 5F form Rock Path)
Foggy = 11F (+ 5F from Forest Path)
Steam = 8F (+ 7 upper + Summit)
Amp = 10F (+ 8F interior + Summit)
Northern = 15F
Quicksand = 10 (+10 Deep + Underground Lake)
Crystal Cave = 11F
Crystal Crossing = 13F (+ Crystal Lake)
Chasm = 8F...
Roughly 199F (I'll keep going)
