NAT/CGNAT IP address/users ratios

Hello NANOG (and friends),

Asking if anyone would care to share their CGNAT and NAT ratios. We're looking at some best practices and I wanted to see what the community at large has seen working, and not working.

I am by no means a NAT expert, and usually I see the other end where it's clearly *not* working.

Does anyone have estimating formulas for devices/users to internal blocks to public IPs?
