IMO, and that of some other respected sources I've read, the most important function of pitch is to achieve maximum contact between the butt and your shoulder pocket. This spreads the effect of recoil out over the full area of the butt, thereby giving you the minimum felt recoil.
I believe pitch has little, if anything, to do with POI. I can imagine it did when shooters shot with their head erect and no regard to cheeking the comb. This would explain the "hockey stick" drops common on older guns, American, especially. We have since learned more consistent shooting is achieved when the cheek is planted against the comb.
I also agree 100% with Chuck's second paragraph. I cut my stocks at a 90 degree angle to the comb and that makes the butt fit my body best. Monte Carlos would be a possible exception. I have no interest at all in what the actual pitch is, by the traditional measurement.
Lot of good thoughts in TW's post. The similarities between his and mine shows we agree on many points. 'Twas not my intent to "Bidenize" his.
