Russ, Large numbers of the Centaur stages in GEO transfer orbit exihibit
quite fast tumbling, and dont seem to slow down quickly. Ron Welch ( Canberra)
automatically classifies any fast flasher moving W-E as a Centaur RB!
The  Milstar3 upper stage (9923B ) which misfired is still tumbling at 
around a flash every second  isnt it, and that has a perigee of 750Km or so. 
Incidentally you talked about one Centaur RB and gave Tle for another!!
