AeroPod, PowerPod and Newton

I went for a ride today and realized that my iBike had profiles for Bike 1 and Bike 2 loaded but I was on Bike 3. "No problem" thought I -- "switch profile after the ride". So I pedaled away and had a nice ride with pretty wacky power numbers, but I was comfortable in the knowledge that I could get the power numbers afterwards.

It occurred to me, though, that the Gen III tries to auto-correct tilt during the ride. So what was it doing during today's ride? Did it try to reconcile the tilt it was registering on Bike 3 with the tilt in Profile 1 (which is from Bike 1 and is definitely different from Bike 3)? Did riding with the iBike set to Profile 1 / Bike 1 while actually on a bike with a steeper stem cause the iBike to start accumulating and applyinig incorrect tilt data to what was a profile that previously worked very, very well for Bike 1?

Does such auto-correction apply only during the actual ride? Or is the data used to modify parameters that are stored from one ride to the next?

I really like the switch-profile-after-the-ride feature, but I don't want to introduce inaccurate tilt data that will throw my previously accurate profiles off.

What I would really like is for the iBike to hold 4 profiles. But for now I just need to understand what it does when you ride with the wrong profile. Thanks!

After you switched the profile after the ride, did you go to tools->analyze power? You need to do that whenever you switch the profile to deal with the different tilts.

Well, I didn't do that previously. Based on your response, I did it and it shows some pretty major power corrections in the 2 miles, then pretty trivial changes after that. But I didn't actually do anything while in that tool -- it was already done. I could choose to Undo Analysis after exiting the tool to return to the massively inflated power readings in the first 2 miles. But I am certain the original numbers (multiple surges to 1000 watts) are wrong, so the post-analysis numbers are definitely more accurate.

So I'm not clear -- is there something I need to do when I go into Tools / Analyze Tilt and Power? It appears the iBike software already did it and it appears the results are immensely more accurate post-analysis. And the only options are Accept and Cancel.

My original question is still of concern -- did a 20 mile ride on Bike 3 with Profile 1 in the iBike affect the future accuracy of Profile 1 on Bike 1?

Thanks!

It sounds like your tilt was off for the first five minutes.

Also, when switching the profile after the ride, you will always want to go to tools->analyze power and this goes through and analyzes the file for that particular profile.

If you accidentally rode with profile 1 you shouldn't have done anything that will affect it's future accuracy. As long as you didn't do a tilt, then in the profile advanced settings hit the "get tilt" button and then resend the profile to the iBike (hard to do all that on accident), then you should be fine.
