You are absolutely right! If you notice, point 28 in the draft (from which you square up to find the neck point) is "1/6 scale plus 3/4" from the front sleeve pitch (point 23). Checking my draft, I either read the 1/12 scale by mistake, or subtracted 3/4 instead of adding. Either way, my neck point is about 1-1/2 inches out of position, so no wonder there are some problems!
I remember being surprised when point 41 (end of lapel) came out very narrow. After scratching my head for awhile, I assumed the "3-1/2 or whatever style demands" was not working for my size for some reason. Should have realized what the math was trying to tell me!
I will draft a new forepart with the neck point in the correct location, plus moving the center front out 1/2" to allow for the amount I took in the back.
BTW I realize now that the wedge you suggested pinning out would have both shortened the roll line and straightened the shoulder. What I spent a couple of hours doing, un-doing and re-doing could have been accomplished in 15 minutes. I guess I need to stop over-thinking and follow directions
