Oh shoot, I made a math mistake (wrong units). There’s actually almost 3 trillion erythrocytes in the human body, which is closer to 8% of the human body (~37.2 trillion cells). Their estimate of epidermal cell number and turnover is more than two orders of magnitude lower.
That still means that erythrocytes are heavily overrepresented in terms of cell turnover (of which they compose 65%), but not by as much as I’d originally thought.

Aha! This makes more sense now. Thanks for chasing that down, I feel much less confused.
