Thank you.
My personal opinion is that almost all glass, CF and composite stocks out there have cheek pieces that are far too large and have too much mass.
The Gen II mold of the SENTINEL reflects my thinking on this in that the CP is much smaller and shaped to help get most eyes into the scope's exit pupil without requiring a lot of head roll-over.
I kept the cheek piece of the Zealot as narrow as possible and still function the way I needed (back of bolt shroud passing under the front of CP on the magnum version as well as nesting down low over the top of the buttstock frame when all the way down.
After 3D printing a number of cross section shapes for the CP, I kept circling back to something close to the Gen II SENTINEL CP. Most face and cheek structures seem to be reasonably comfortable against this profile.
If your stock's cheek piece is too wide, it will always force your head laterally away from the exit pupil regardless of the height setting. This in turn forces excessive head rollover (when we would like to have that as close to zero as possible).
So my thinking is that the user can always add more width with the usual grunt materials but it is usually damned hard to make the width less than delivered.
Here is a cross section with your widths at different locations working.
