Then I aim for what you might call a "feeler gauge fit" with the smaller key and "elastic interference" with the larger.
Using this technique I find that I can easily discern whether I am holding both the outer surface of the belt and also the allen key accurately parallel to the pulley axis. This is not possible if the allen key is simply forced through the gap in the conventional way
Hope that makes sense .. particularly the last bit. Its hard to put into words ..

This helped, thanks utopia!
Yeh, if I felt the key get cocked, then I'd simply disregard that "reading" and try again.
Your suggestion made it much easier to alight the key correctly and get a good read every time - cool!
