Why not just fix the tool? G

My DJ-20 rarely finds 90 degrees all by itself. Three seconds with the
6" combo square in my pocket and a twist on one lever makes it all
perfect. It's so easy that I no longer bother to fine tune the 90
degree stop.

The same can be said for all blades and miter gauges. 10 seconds of
checking can save a bunch of rework and wasted material.
