Does DL remove/reset upgrade inventory?

I had a flight alert set for my SFO-MSP segment in 2 weeks and had an alert set to notify me if less than 3 seats in V inventory were available. Got the alert yesterday letting me know inventory was gone, which I found odd considering it was a 75X with 7 rows in F. I went back to EF that night to check it out, and low and behold it was saying my flight had V8 and G7.

Just wondering if it was an EF glitch, or if DL removed all inventory and then later added it back in? Anyone see this before?

I have seen what appeared to be the removal of V inventory just before the UG windows opened.

Never mind, I completely forgot that I set an alert for U inventory a couple days before I bought the ticket. Once I purchased the ticket I set up an alert for the upgrade inventory, completely forgetting about the first alert.

The email I received was for U, and not for V.

DL definitely adds and subtracts UG/award inventory, but by what algorithms I have no idea.

EF is usually quick to respond when someone posts a question that has something to do with them.
