BTDT, expected that answer (you *were* going to ask).  Ok, now the next step, 
do you at least remember what exactly was out of spec?  We could walk thru 
that exercise.

Phil, if you get yourself a copy of Dave E's 885140, you will quickly realize 
that torque allocation happens for two reasons, acceleration while turning 
due to relative slip angles, and/or traction on a given wheel.

Going from 'that' concept to an alignment, seems difficult to accept or even 
understand.  One needs to ask the question, what did your alignment do to 
affect relative slip angles while turning or due to traction?  If any effect, 
wouldn't some other relative slip angle of the wheels reproduce (effectively) 
the same 'out of alignment' torque allocation?

Alignment (<insert>: improved, induced, corrected) slip angle torque 
distribution can be copied by changing relative slip angle or the radius of a 
given turn itself.

Please do present your argument more clearly, or drop it.  My guess is that 
even Dave E is not with you anymore on this one.  Dave's quiz would be next.

Bottom Line:  Without data, I will make the claim that I have dutifully put 
several T44 chassis on a calibrated alignment machine, and performed the 
correct per audi (updated) specifications (as close to "exact" as possible) 
and still got spider bite. Now what?  Phil?
