Miff posted this a few days ago as well. I had an email dialogue with Peterson that I used for my DRF Expo presentation (displayed as "Changing Track Speeds" in the Archive section here), obviously have serious respect for the work he does, and have found a lot of his findings to be true, coming at it from another direction.

Having said that, I keep waiting for someone to raise the obvious question about his track bias comments. Curtis? Are you ready to use the nine letter A word?
