This is how it was explained to me.

Platinum are upgraded first. They should clear if there is room. I don't know how it works if there is only room for some.

Gold are upgraded second. Again, I don't know how it works if only some are going to clear.

Then, silvers are upgraded in 24 hours in advance, but lately they have not been upgrading me except at the airport. If this is the case, and there are seats available but the silvers have not been upgraded before the silvers get to the airport, Delta makes the list by the time of your check-in on line.

So, I guess we are both right.
