There are several things here, but let's look at this: The differential formula must include the tangential effect, since using tangential feed naturally creates a helix angle. I don't have specific Pfauter info, but there should be additional formulas for lead that include a "delta" value which is computed based on the tangential formula and its constant.
If you send me copies of your Pfauter pages, maybe there's enough there that I could send you some answers.
