The Gen 3 iBike takes about the first 5 minutes of the ride to find its Tilt, then everything is good, When you hit Trip reset does the Gen 3 have to go through its 5 minutes again? Also during this 5 minutes or so does it revert to the last Tilt cal you have done?

Thank you for your help and information

My experience is a trip reset sees the 5 minute start up begin again, a lap reset does not, so if you warm up prior to a race, then hit lap reset for the race itself then first 5 mins of the race lap are ok.

It seems to me that this problem should be solvable. Tweak the calibration riding tilt number determined by the calibration ride that is used for the first 5 minutes so that it roughly equals the average of the dynamic riding tilt numbers determined after the first 5 minutes.

Is it not the case that this first 5 minutes is recalculated in the IB3 software and corrected, so that what we see when we view the ride file is what it would have been had we done a tilt calibration?
Can someone confirm this?
My reason for suggesting it is my ride yesterday. If I click into the box to the right of the "analysis status" profile info, I see the power and slope info change to what I believe I was seeing when I went out.

I am still trying to come to terms with the units I have so forgive me if I am stating the obvious, or if what I have written has nothing to do with the original post!

Snow? It was 95F here in the San Francisco bay area yesterday.

If you are getting good power numbers in the first few minutes of your ride by not doing a trip reset, then the iBike's current calibration must be well matched to your initial riding conditions. And if you get bad numbers initially when you do a trip reset, then the calibration employed by the trip reset must be wrong. So the question is how to get the latter calibration equal to the former.

What changes? It must be related to riding tilt, as this is the only thing that has been discussed as changing during the ride.

There are 3 riding tilt numbers. (1) the one associated with the tilt calibration (the 180 bike swap dance). (2) the riding tilt found during the calibration ride. (3) the dynamic riding tilt found and updated during the ride.

It seems to me if your profile has a correct (1) and (2) equals the average of (3), then the first few minutes of a ride after a trip reset should be good.

What else could it be?

My iSport almost always gives good numbers in the first few minutes. The only exception is when I spin the front wheel of my bike a lot when cleaning on a bike stand. Doing that sometimes seems to screw things up so that I get bad numbers in the first few minutes on my next ride. So after a wash I redo a bike tilt and also a trip reset. This seems to work as I almost always see good numbers.
