‘Hours’ hike estimates are low for me on high altitude hikes

Great data tracking, Art, thanks!

Did you calibrate using a FIT dataset? If so, can you post a screenshot of the altitude calibration chart that appears on the Ingest tab in the Calibration Modal?

Also – did you activate both of the altitude model settings on the Plan Inputs tab, just one (if so, which one), or neither?

Thanks for suggestion to try FIT dataset.  I created one Calibration Profile using high altitude FIT data from both treks; Ralakung and Kilimanjaro.  That made the error worse.  I then created a second Profile using data only from one trek; Ralakung.  But I am not able to figure out how to switch from the first to the second Calibration Profile.

I’ll explain my Altitude settings after I resolve how to change Calibration Profile.  I used appropriate settings for each trek.  I was acclimated on both Ralakung treks and the second Kilimanjaro trek. 

This shows the altitude calibration chart I created using data from two different days during the trek.

And this shows the TRIPS estimate for walk time using the calibration profile.  The calibration profile was created by combining the FIT data for these two days.  Actual walk time is about 80 % of estimated time.  To net it out, the uncalibrated estimate is low, the calibrated estimate is high.
