I'm sure every sensor is different, but I'm just curious what you guys are finding as far as reliability. We're just not having good luck. I really want to like the CGM, but I totally understand why my son thinks it's worthless. Here are some numbers from the sensor that was started on Friday night. I'll put the finger prick meter readings in parentheses. Saturday 20 min after lunch: 68 and dropping (meter said 118)20 minutes later, G4 said 149 steady (meter said 105) evening G4 said 172 steady (meter said 127) late night G4 said 143 and rising (meter said 120)Sunday night G4 said 76 steady (meter said 112) Monday mid-morning G4 said 174 steady (meter said 140) late night, 1 hr after snacking, G4 said 121 steady (meter said 173)Tuesday an hour after lunch, G4 said 59 steady (meter said 82) Also, it doesn't seem to understand calibration the way I do. Just now, the G4 said 136 steady, and the meter said 138. Woohoo! But after entering the 138 as a calibration, the G4 said 136 and dropping. Doesn't make sense to me. Is this pretty normal for the G4? Are we just expecting too much from it?
