And for those interested in useless trivia, I believe the reason these codes are used stems from an era when DB memory was expensive enough that you actually cared how many bytes each field used. That's why they used "1K" instead of the more logical "100K".

Then, the "1P" and "2P" were used somewhat in reverse of what you might expect so that when the status needed to be part of an order-by clause (say, as part of a sort to determine an upgrade waiting list), the code could be kept very simple. Sort ascending, 1K, 1P, 2P.

I wasn't aware of the 3P. I guess following the above logic, a "gifted" Premier comes after a "normal" Premier on waitlists (assuming they've reached a point where status is the tiebreaker). Makes sense...
