The TPW date is the date that is shown in the 'note' just under your status. I emailed Eric at Classic Chevrolet to confirm this on the 18th.
The odd thing is, I went to 3000 on 5/18 and then I got another email this morning 5/20 saying the same thing that my status was at 3000. It was just odd!
Still at 3000 and still a 6/7/2010 TPW!
