Hi Ryan, I used Garmin devices and their Connect-service for a long time and think I have a rudimentary understanding how it all works. Most of Garmin’s health and fitness metrics are calculated on-device instead of in-the-cloud. This means you get more data by buying into the higher-tier devices or upgrading your older gear (always check which features are supported, if a certain metric is important to you). In this case; buying a Fenix 5 “unlocked” your FTP estimate ([→ Source](https://www8.garmin.com/manuals/webhelp/fenix5/EN-US/GUID-B40A5128-C382-4F10-AD38-39649C42EF35.html)). It’s tricky to say which specific activity made this estimate possible, since Garmin uses (their now owned) Firstbeat Analytics and a lot of data points in your previous activities to come up with their numbers ([→ Source](https://www.firstbeatanalytics.com/en/features/functional-threshold-power-ftp/)). I think your watch and Garmin Connect synchronized all activities including SUF (and possibly the last missing metric for the estimate) either on the day of the mountain ride or even a day after. Hence the delayed reporting. Personally, I would trust the numbers from your Full Frontal Fitness Test and ignore Garmin’s guesses. If your workouts are feeling too easy, maybe it’s time for a re-test on The Sufferfest. Just ask yourself: [Are-you-training-with-accurate-4dp-targets?](https://wahoox.forum.wahoofitness.com/t/from-the-coaches-are-you-training-with-accurate-4dp-targets/5038) Anyway, just my two cents. I hope this helps. --- _[View the full topic](https://wahoox.forum.wahoofitness.com/t/garmin-ftp-estimate/10722)._
