Neck pullup shim size formula?

[robertdo]

A VERY crude diagram of what I understand is a pull-up

a 0.5mm shim would create a additional 1 degree angle (give or take) with a 30mm high ribs violin at the top block. In return this 1 degree angle would increase the height at the bridge by about 3.5mm (nearly 7 times as D. Burgess and Fiddlecollector said) if you consider a 198mm string length from the edge to the bridge

Nb. The shim is the small black rectangle. The longer gray rectangle is the top block

I don't agree that a carefully matched maple shim under the fingerboard necessarily looks bad. A butcher will make any wood look bad.

You could argue that the colour matching could be better, but the flame match is not too bad...
