It is as many opinions as there are mechanics.
I wouldn't want my customers to leave the shop with 10% braking surface when they can have almost 100%.
It takes longer than you think before the pads have gotten the curved shape of a worn rotor.
You would also be surprised over how many rotors that are actually warped when put up in a lathe even though you didn't feel anything while driving. The little vibrations are soaked up by bushings and ball joints and put more wear and tear on those items if continued.
The only thing I do when resurfacing is to remove the high spots and return the rotor to flat surface. The alredy low spots are almost untouched by the lathe.
Also by not resurfacing you get some strange hot spot symptoms that can warp the rotor when the new pads 10% surface needs to stop the whole car.
If the rotor is below minimum, then it should be replaced anyway.
But as I said, this is only my point shared with 50% of the mechanics out there.
