Assuming that you match the power targets at each step, and don’t have wild variation, when you hit the 19:30 point in the test, you are matching the FTP that is present in the settings at the start of the test.
- Blow up and stop BEFORE 19:30, you will be assessed with a LOWER FTP than the starting FTP.
- Blow up and stop AFTER 19:30, you will be assessed with a HIGHER FTP than the starting FTP.
- Additionally, there is some magic detection and math in the system that will adjust your FTP based on undesired variation in the final parts of your test (the highest 5-minute power range).
If you got well past the 19:30 point in the Ramp, and were given an FTP that is lower than you started, that means TrainerRoad detected notable variations in your highest 5-minute power (that usually is the last 5 minutes prior to you blowing up)… OR you were not actually matching the power target towards the final minute or two before you stopped.
If you share a link to your ramp test (copy/paste the file path from a web browser viewing your test), and make sure your TR account is public, we can do some review.
