On most my lenses, between major f-stops, here are 2 demarkations, like so:

f/11
-
-
f/16
-
-
f/22
-
-
f/32

Each of the larger f-stops is 1 stop faster -- 2x as much exposure for a given time -- than the preceding one. So are the increments 1.33x and 1.67x faster than the larger numbered stop?

I.e., does that correspond to:

f/11
- f/13.1
- f/14.6
f/16
- f/18.5
- f/20.7
f/22
- f/26.1
- f/29.18
f/32
