Hello! Calling on to the knowledge of the group.

How do I determine the correct amount of additional pops per stop?

Is my math correct?

1 pop; initial exposure e.g. f/8
2 pops; +1 stop e.g. f/16
4 pops; +2 stops. e.g. f/32
8 pops; +3 stops. e.g. f/64
16 pops; +4 stops. Etc.
32 pops; +5 stops
Etc.

So this being the case, if I needed to add 2 stops for my bellows compensation that means, I would have done 5 pops or 8 pops?

Thanks!
