But isn't there a distinct disadvantage to being absent from the EUA list and relying solely on the "battlefield" (ugh, I hate that term) upgrade? This same thing happens to me when the first flight is on UA and I am connecting to CO - you can't check in on CO - you won't even get the option to do so. I always do check in with UA first, but that doesn't seem to trigger anything perceptible in terms of your place in the upgrade queue.

You have it backwards. When you check in with UA and your second flight is on CO, you are still on the EUA list (you are always on the EUA list when your CO Elite FF# is in the reservation). Checking in with another airline only prevents you from being on the Battlefield Upgrade List. This can be corrected by seeing a gate agent and having her manually adding you to the list.
I'll admit I never checked in first for the CO flight before I go the UA desk at the airport. I generally don't do E-checkins, especially on foreign itineraries, as I just don't see the benefits of doing so.
And a double admission: this has never actually affected me as I always schedule above the minimum layover time to minimize the chance of a misconnection - and then CO always cheerfully moves me onto the earlier flight, when I don't need the plus-size pad.

Correct, as you must check in with CO to be added to the list on the PDA site. But that list is only used at the gate, not for EUAs. The EUA queue is generated dynamically each time the process runs and if you are elite then you'll be included. That's what the agent the OP was talking to saw and commented on.
