Honestly, I still don't have enough experience to make a good test subject myself yet
Can you test that theory by just threading your stock collar on backwards?
Actually, you might make a better test subject... no preconceived ideas.

Can't really thread it backwards... the internal stop is at the other end of the collar.
I did make a comparison both with and without the collar... using a reference line on the stone as a guide...

... in the top row, you can see the '0' on the knife jig stays pretty much on top of the USB. But with the stop collar, it pulls it well below the line. So if the width of the collar was reduced... this factor would be nearly eliminated.
Without the collar, you actually can still use the jig to maintain the angle... as long as you keep the blade at the same reference point/line. (Sort of a "guided freehand").
Obviously, some of this depends on the knife length. Longer kitchen knives, knives without much 'belly' etc. won't be influenced as much. But I tend to sharpen more EDC/pocket knives, small hunting/camping knives, etc. where this is seen more.
