Award/Upgrade Algorithm Characteristics
I've been checking upgrade seats for my daughter's trip to/from FRA. It appears to me that the award seats (XC & NC) increase dramatically at about 60 days out. For the last few days I've seen NC go from "0" to "9" on successive days--today (12/17) NC is at "9" for UA 917 on 02/14/05 (FRA-IAD); yesterday it was at "0".
Over the last several days award/upgrade seats have increased from "0" or "1" to "9" on a progressively daily basis. This may be useless knowledge for many folks, but some of the hardcore among us may find it interesting. It may give a clue on when an upgrade may clear, at least for European markets.

Is the behavior different for a 747 vs. a 777?

It may be using a pretty complex yield-management algorithm, not one that can be cracked by looking only at a specific flight on a specific date.

Read the UA sticky at the top of this forum, and locate ozstamps' excellent " Thread listing all known UA revenue and award booking codes and a summary of each one"
For the lazy, it's here: http://www.flyertalk.com/forum/showthread.php?t=113792
It tells you what everything means, and how to see it as well.
