There are a few percentage points missing in that equation.
Yeah, I am certain the demographics have changed. If anything, probably in a way favorable to their AP strategy. Tal'Dorei is straight "generic" D&D that can accommodate any FR material easily enough, and Mercer will gladly offer suggestions for setting a specific AP in Tal'Dorei if asked on Twitter. Considering how much he contributed to Dragon Heist, I am certain he has specific suggestions for conversion (myself, I say just plop Waterdeep on the Menagerie Coast, make the Drow mafia into Xhorasian spies and go).
Typo.
I meant 35% for Realms (which is what the linked thread refers to).
