A fitness breakthrough is achieved when your power exceeds the Maximum Power Available predicted by Xert for your fitness signature and represents a maximal effort. Generally speaking, it will require you to surpass your MPA for at least 5 seconds during an activity. The longer you exceed MPA, the bigger the resulting fitness breakthrough will be.
When a fitness breakthrough is seen in your data, your fitness signature is extracted and updated. Most of the time, if your breakthrough included moments where your power exceeded MPA, you receive a medal on your Garmin MPA or a breakthrough notification in Xert EBC. Depending on your effort, one or more of your Fitness Signature parameters may increase.
If you came very close but didn’t surpass your MPA, your Fitness Signature may decline. This is a near breakthrough, or colloquially a fakethrough.

After a (near) breakthrough is detected, Xert re-calculates your MPA data using the NEW fitness signature… to visualize this, move the image slider below to the right. Clicking ‘Previous‘ at the bottom of the activity details page will show the MPA data using the starting/out-dated fitness signature – the MPA data should align with what you saw on your Garmin or EBC app during the ride… to visualize this, move the image slider to the left.
