Again i have actually done this and it is easy to adjust it in small amounts. if that does not get it perfect then an alignment shop may be able to make the final small adjustment with the actual suspension and steering parts.
I'm not saying he can't get it close. Or if lucky that he might get it spot on visually. But that he should be forewarned that it may not be a perfect adjustment. And what one person perceives as perfect or almost perfect or good enough varies. I'm just providing as much objectivity as I can.
That said, going back to the technical aspect, smaller splines in that of itself means nothing. A given spine size will have more on a larger diameter shaft than it would a smaller one. Without qualifying that aspect of it, it again comes down to subjectivity. A given number of splines will offer the same adjustment no matter what since it will always be related to the number of degrees whether its a small shaft or a big one.
