Ferrll, There are at least a few more days from an orbital standpoint, and so far the electronics are holding up. BOTE calculation gives a descent rate approaching 5 km/day, and rapidly increasing. Just remember that as a practical matter it will be impossible to have Keps with the accuracy

Farrell,   An often used rule-of-thumb in astrodynamics for decay height is about 140 kilometers which is about 87 miles.  A satellite that gets that far into the atmosophere will burn up during   it's final orbit in short order!  I would recommend you just keep trying until you are sure the
