i.e was it x,000 or x,500 ?

I only ask because of a very long e-mail conversation I've been having with them over a few months... in which near the end (among many unrelated things) I made a suggestion that they estimate avg balances for 11/30 and correct later. And I noticed that my avg mileage balance was certainly not x5,000 yet, they gave x,500 in miles.

Or perhaps it is simply a coincidence for me.
