I had mentioned in another thread that my theory for why some of us were seeing new sensors not last as long as before had to do not with the sensors themselves, but with the receivers (that have had their software updated):

I have been using a new sensor & transmitter with 2 different receivers (thanks to Clare, I didn't know that was possible :-) for 10 days now.
One receiver was my old one that I have had for 15 months (revision number: 2.0.1.104) and one is the new replacement receiver I got this past January (revision number: 2.0.1.158).
I got the flu yesterday so this morning I took a bath and had both receivers right next to one another and noticed this when I came out of my bath:
Can you guess which receiver is the new one?
The receiver that didn’t miss a signal was my old one with revision number: 2.0.1.104, and the receiver below it (that missed 2 data points given the exact same broadcast signal from the same exact transmitter is my new receiver with revision number: 2.0.1.154.
Given that the receivers were right next to one another, the only other explanation that I could think of was that the receivers took their readings at different times… but this is not the case because when my sugars go low they both alert me at the exact same time (the beeps are in sync with one another) so it must be the transmitter that broadcasts every 5 minutes (rather then the receiver that accepts the signal when it decides to).
Anyway, this is obviously just one data point (or 2 points in this case but it does seem very odd that 2 receivers getting the exact same signal would yield such different results.
It’s almost as if the new revision number does not trust the readings it gets from its own transmitter or something!
