Spike or Error

This isnt the first time i’ve seen this flag. Today’s ride was loaded and I get the popup saying i have spikes or errors in the file. I looked at it in Golden Cheetah and fit file repair tool. found a few abnormal data entries. I cleaned them up and reloaded the new FIT file. I still get this error. It was a great ride with a nice breakthrough, but Xert isn’t updating fitness signature due to the errors. I can’t find these spikes or errors. Spikes or errors

It might be that your maximal effort is too short for the extraction to be used. You may look to do manual MPA analysis and adjust.
