If you go to "Manage Bookings" and enter your ticket number, you will be able to see relatively more information about your coupon than most other sites, including the complete fare basis.

Huh. Maybe it force-clears to the lowest open inventory, which will be a revenue bucket if R, PN, and ZN are not available. In OP's case, F was the only option so it cleared the upgrade into F inventory. That's going to be my hypothesis, since $309 is way more than the fare differential for that route.
OP - if you check your receipt, does it call the add/collect an upgrade fee? If so, I think my guess would be correct. I wonder if this "feature" means you earn 1.5x PQM...
