Perhaps a field with the finish cut depth and add that to the final diameter before running? Then run the finish cut. Never mind it looks like it's already there. Maybe it's the new glasses. Rick G

I did a complete re-write of the OD sub this morning as there were several mistakes in my logic...

This sub will allow you to specify roughing and finishing tools, depth of cut, feed as well as the normal things needed like OD, final diameter, start Z, end Z. If the finish cut is equal to or deeper than the difference between start diameter and final diameter / 2 then the roughing cuts are simply skipped. The roughing cuts are as close as possible to the specified roughing depth and not deeper but evenly divided up so each cut is the same. The finish cut follows the complete profile left to give a wiping cut on the Z shoulder.

And here it is completely re-written and much better behaved...
