uc_tracking results don't match fedex.com prior to pickup?

Hmm... Here's what was happening:

Each scan of the package results in an "Event". In most cases, there are many events. This module iterates through the events using the code foreach ($reply->Events as $event). This is the problem. When there are many events, $reply->Events will be an array and PHP will loop and set $event to each event object in turn. But when there is only one event (like in your case), $reply->Events will be an object, not an array, and PHP will iterates over all the member variables of the event object, resulting in bad data. I have committed the fix to the dev version.
