I'm probably the odd one, but I use my Park TS2 and flip flop the wheel. If it is off center, I need to calibrate my stand. I have an inexpensive dishing tool to double check I didn't do something stupid.

I don't know how accurate it has to be as I doubt frames are perfectly aligned. I can't imagine the tolerance on a frame is closer that most dishing tools. The one caveat may be carbon fibre bikes out of molds. I can see close tolerances on those. I'll still defer to a properly setup trying stand.
