I hate it when the shop doing the turning just cranks in .010-.015" on the tool without giving any consideration to making the rotor last a little bit longer.

I always took the minimum amount possible . Usually .002 per side at a time until they were true, then I would do a slow pass at .0005 per side, followed by a da sander with 80 grit while the rotor was still spinning on the machine .
The finish was a perfect non directional finish, and pads bedded perfectly almost every time .
Now, we just replace with chineese iron .
I think the whole pad deposit thing, is just an attempt by the brake manufactures to skate warrantying parts . They do not honor warranties due to warpage, or corrosion , which are the 2 main reasons I replace rotors on a daily basis .
Just my whack job theory, so take it for what it is worth .
