The 3-hour EUA ending time has been gone for a while. EUA runs until checkin close.

Flight had 19 people on the standby upgrade list, some of whom were 1K's at the top. No upgrades processed until the gate and only one seat was available because someone else either purchased a seat up front or took a bump off an earlier oversold flight.
Just because you see "R" space does not mean CPU will happen.

They are using the "R" bucket, but EUA has some logic in it that doesn't process upgrades on certain flights that fall below a certain amount of R inventory which seems to be defined by flight or market.
I don't think there's some hidden bucket as much as they have some additional logic not to release below X on certain flights.
