Making wheels concentric with bore.

This is not how the pros do things but I have my ways to get it as good as I can. So I have a pin guage set up in my drill press and measured the run out to be .001 and figure I won't get it any closer than that....ive tried in the past and only lost more hair trying. So what I do is put the wheel on and measure it. I get .007 so I know where I'm starting at. Then my mind wanders and I start rotating the Chuck a quarter turn turn and find that I have .005 at 180°. I guess this coincides with my .001 on the pin and my total starting runout is .006. So my question is should I rotate my wheel on the pin so the high side lines up with the .001 side of the pin or opposite or does it not matter? My mind is drawing a blank on this one.
 
If you were able to file it or cut it round to your drill the wheel when done will only be off the .001 the pin gauge is off. How the wheel is positioned doesn't matter unless it keeps spinning on your pin. If it spins them your always cutting on that last .001. Does that make sense. If you don't match the high with the low it will just require you to take more off the outer dia to get what you are looking for.
