In running Quicksat predictions a week ahead, I got a very large time uncertainty for the TRMM predictions just three days from now. So I went to OIG and got the latest five element sets. The most recent one (day 00120.8) has a significant negative drag, showing a very recent maneuver, I presume. I don't know how different prediction programs handle such negative drag, but I thought I'd mention it as I think it's at least possible that it could yield unreliable predictions.
