Joe,
I like the jig and may get one for my next crown project. My miter saw is about 15 years old and Bosch has since changed the design and you can no longer find the crown jigs made to fit it. The one you linked doesn't attach to the saw and is universal.
I'd love a tool that told you want angles to set to utilize the compound feature. The directions give you an angle for "standard" crown, whatever the heck that is. You'd think you could say set the compound at XX degrees for 4" crown, XY degrees for 4.5" crown, YY degrees for 6" crown, etc. A table would be great. The jig is nice because you set it and all your cuts are consistent.
The height of the crown doesn't change the angle.
The angle of the back is what might change.
THe easy way to find that angle is have a piece of 3" with the same back angle cut that standing up and then lay it down and set the saw to match that.
Somewhere I have a book of angles that came with the radial arm saw.
Finding something like 31.6 degrees never really helped.
