[O.B.Left]

Its my personal opinion that Homer would often deduce the range of possibilities for components. Theoretical maximum and zero say at either end of the range. The results at the opposite extremes, though logical and indeed correct are not necessarily common. So it is with Total Motion, Zero Shift in my opinion. (Shorter shots, zero shift is common.)

Zero shift in a shaft plane sense is rare , but Homer also described a clubhead only plane of motion, zero shift. Where the clubhead travels the TSP but not the clubshaft. Not exactly common either, but perhaps easier to pull off.

gmbtempe....even Moe with his super high hands had a slight shift. I cant think of anyone who meets the criteria personally, but I could be wrong. Me being wrong is well with in the theoretical range of possibilities after all.
