Thanks for the suggestions. Because the difference from front to back
is so extreme (more than 1/4 inch), I haven't been very precise in my
measurements. I'm trying to just get it in the ballpark before
bothering with precision.

But to answer your question, I'm measuring with a stick clamped to the
miter bar. The stick has a screw in the end. Not the ultimate in
precision, I know, but good enough to get a least kinda close, I would
hope.
