> [@ned](#): > > do you think I should wait to calibrate until the Dex is reading steady, even if the Dex is asking me to calibrate? @ned, I absolutely think that your calibration will be cleaner if you wait until the Dexcom and the real BG have been flat for a while. It is very likely that the Dexcom looks forward when it calibrates, but it cannot predict the actual BG curve. The only situation where the Dexcom may be able to anticipate a non-flat situation is if the rise or fall is constant and steady. Even then, though, I would wait. The only times when we don’t wait are: - upon sensor start (we want to see a signal, even if we know it’s not perfect) - if we know there is a very large error. In that case, it makes sense to reduce it already, and to do an extra calibration later if you can or want to. As a caveat, a teenager’s BG is so quarely that we sometimes see periods of 6-8 hours where we are unable to calibrate properly ☹ ---

> [@ned](#): > > here’s a comparison of the OneTouch Verio IQ, True Metrix Go, and Dexcom G5. @Ned, I am very impressed by the concordance between your Verio numbers and your True Metrix: the difference is minute. Like @docslotnick, I agree that the behavior of your Dexcom is textbook: it slightly trails your real signal, just as we expect it would. The graph was great! ---

> [@ned](#): > > do you think I should wait to calibrate until the Dex is reading steady, even if the Dex is asking me to calibrate? The Dex will ask you based on a strict time schedule. Definitely wait until it’s flat to calibrate. There’s no need to respond instantly to its requests. Personally, I only end up calibrating about once a day on average, and it works great (and I think would be far superior to twice a day calibrations at times when it’s rapidly changing), but that’s based on experience that that works fine for _me_ (I increase frequency if my sensor seems wackier than usual or something is going on to make me not trust the readings as much). ---

Just for info, I think we only calibrate once for every 2 days or so (through lack of diligence). Doesn’t seem to affect things for the worse at all. In fact, I think our results are better than they were when we were calibrating more often. This is probably due to not always calibrating when things were exactly flat.
