Where 100"*[1COS(30)] would be 84.6" (I believe this).

Mike,
I think you have COS confused with SIN (or degrees confused with Radians).
COS of zero degrees is 1.0 [cos(0) = 1] so if the look angle is zero degrees, you multiply the drop by 1.0 (no change).
If the look angle is 30 degrees, COS(30) = 0.87; so you would multiply the drop by .87.
If we applied your equation (drop*[1cos(@)]), the drop would be zero for all level shots: drop*[11].
I'm pretty sure you multiply the drop by the COS (cosine) of the look angle.
