Any first-hand experience with PDA or Trackmasters?

Not to sound rude or ignorant but I’m more looking for “they are lax like Shattenbaum PCA” or “their run groups suck” more than “seat time vs autox” - no shit, 4 20-25-30 min sessions had damn well BETTER yield > autox for almost $300/day (hence my reservation, I can go with PCA to the Glen for about 300 for TWO days).
