I hope you misplaced a decimal point. :-)

For 20 TPI I get an infeed of 0.038" on the angled compound or 0.032"
on the crossfeed, assuming the tip flat width is 0.006" and you zero
the dials when it contacts the work. Also close the halfnuts at any
line on the threading indicator. I haven't thoroughly tested the
spreadsheet's accuracy since I don't reshape the tip for every job,
but it's close.
