Measuring brace height

[ChuckC]

Maybe its a bit of both.  

It was already stated that it really doesn't matter how you do it, as long as you do it the same each time.  Just like it doesn't matter a bit if your spine machine says 50 or 100, as long as YOU know what your arrow needs are and do the needed background work to determine that.

They used to use their thumbs for a lot of years.  How many of us have the same "fistmele" ?

I was always told the reason for the indent is that when the square is clipped on the string there is clearance for the nock set. That way the square remains square while checking the nocking point and brace height.
