150%. I've been upgraded on all 6 booked segments and flown 4 since May 1. I was really surprised when I used the same-day confirmed option to change my outbound flight three hours before and *still* cleared the upgrade list---at the airport, granted. Of course, I went out of my way to make sure I was booked on 757 equipment, which has by far and away the highest F/Y ratio in the fleet. In fact, on the final segment (SLC-SAN) there were even 10 empty seats in F.
Of course, I would be remiss if I didn't note I also cleared on 100% of my UA flights this week (one of which was also changed ~3 hours before departure) as well, and I don't even have status on UA this year...
