Handwheels again?!? was Re: true closed loop vs. hobby closed loop

John,

Please tell me ONE thing you can do faster manually than with a
computer controlled 3 axis powerfeed, with dro readouts (which is
just another name for CNC, leaving out the "program" capability)

Even a single hole drilled, or a single straight line cut, will be
more quickly and more easily done; AND more accurately; WITH CNC
jogging, if not MDI...

I keep hearing this "in-favor-of-handwheels-argument", but let's hear
WHAT exactly is "faster" or "easier" without CNC. Cmon, Just name one
thing...?!?
