Am I missing something here???

It doesn't take much torque to simply turn the leadscrew (and, presumably,
move the carriage. But, when you are trying to take a heavy cut, the torque
can be pretty substantial...

I think that you did miss it. I can be too brief in my posts, so it was
probably easily missed: I took the torque measurement during a heavy
cut, the heaviest that I would expect to make (.050" DOC & .050 advance,
IIRC - it's not a heavy lathe).
