Gosh, was that a month? Time flies - remember, mine was activated a day after yours.
Mine also continues to perform well, sync rates (according to Zen portal) of circa 50/9.5, which is far more than I expected and so far, hasn't changed.
Oddly enough, according to the Zen portal, I also had 3 resyncs between midnight and 1am this morning, these being the only drops so far apart from those caused by me powering modem off when experimenting. In each case there was apparently no change whatsoever in DS or US rate, so I wonder if it was false reporting somehow? Still relying n BT's locked down modem, so unable to get any independent stats to verify.
