I just went back to mach3 to test. The Shortest Rotation function works perfectly. Teh 360 rollover is busted. I checked back in some OLD OLD OLD test notes for Mach3 and it was broken when implemeted and ART as it seems never got back to fix it before he tired.
That is all there is folks. IF you still think that UCCNC does it correctly then that is fine by me. NO problemo
