I assume you mean that the *internal* jaws would have been a better way
to do it.

Well, more that the way shown in the picture doesn't offer much in the
way of a real measurement at all does it, especially if using a verity
of verniers?

The only reason one might not use the internal jaws might be in case
you cut the belt?

Or get any measurement you like by stretching?

Well, yes, but I have measured things like that and you can generally
get a measurement before say the belt goes completely tight. That will
give you a ballpark figure at least and possibly easier / more
accurate than trying to measure the diameter or circumference of a
'live' often non-circular rubber 'band'. ;-)

One other method is to try and find a round object that it just fits on
then measure that

Yes to all. Just how the angled-sides of the jaws could be thought to
measure with any degree of accuracy I dion't know. Apart from the belt
sliding toward the pointy end, it's at an angle on the jaws - the
width of which are "undefined" :-)
Just wonder how they thought measuring like that could in any way give
a sensible answer. Looks like guesswork.
