I'm pretty sure this is a bug as I can't think of any reason that it should be a feature.
I let PT3 observer a few tables on Full Tilt yesterday for a few hours. When I got home, I switched the active database over to my observed hands db and ran table tracker to go fish hunting. Found a couple good prospects, switched db back to played hands (although it doesn't really make a difference) and sat down at the table. Once we started playing the HUD showed the stats from the observed hands db but would not update to reflect the additional hands that I've actually played with the fish. If I hovered over any particular stat it would show the correct stats in "this session" but it was not adding them into the total stats there either.
Both dbs are checked in the HUD configuration to be accessed and it does appear to be accessing them both, just not adding them together.
