In the keating equations that same tilt is then further used to compensate the dioptric power matrix for the tangential, saggital, and torsional components, which are then further used to compensate the cylinder axis. I would assume that the polarized filter should be treated more as a cylinder axis than as a effective tilt angle.

I think I may have a solution:

From the article

- Use equation (17) to find the effective tilt angle.
- Use equation (19) to find the tangential meridian expressed in the lens' local co-ordinate system.

Since the effective coordinate system is A degrees off from the local coordinate system wouldn't we jst block up the lenses -A degrees off? And if this thinking is correct then wouldn't it mean that technically progressives and FT's with their films aligned along the 180 with no way of realigning them are not a good option in high wrap frames?
