My calculation results are in my signature. They exclude planes that do not have an F. They separate out if an instrument was used and is per leg. ie. I may use one GPU on EWR-SFO-TPE but fail to upgrade on EWR-SFO so I count that as one failed GPU and one successful GPU eventhough I only use done.

I don't have enough room to post the metric based on MILES which in a way is more meaningful since people will tend to get upgraded more easily on short flights vs long DOMESTIC flights.

This year has prob been my worst year for upgrades

I also have been keeping a running tally of RDM I've "lost" since they changed to the revenue based system.
