There's no way around the fact that the math has to work right in the end, but 
in the meantime I suspect that the problem you saw was due to rust/dirt that 
gets in the splines and keeps them from mating perfectly. This is probably much 
more of a problem in rust belt cars like ours. By necessity, there must be slop 
in the fit, so there is room for dirt to fall in there and introduce some 
uncertainty. My guess is that this goes away; after driving for awhile, 
assuming the dirt might get pulverized or work its way out of there.  

OTOH, I can't explain why both sides repeated so nicely.

I checked, the front outside splines have 31 teeth, which works out to 11.61 
degrees per tooth.
