Real time TSS
This is something I've wondered about since getting the Garmin 500. There is a data field for TSS, but how can the unit give TSS without knowing you're FTP? My understanding is that The formula for TSS is....(seconds X NP X IF)/(FTP X 3600) X 100. So if the unit doesn't know what the FTP is how can it calculate TSS, or even IF for that matter, since IF is NP/FTP ? Or is there a way to program in the FTP that I'm unaware of?
I just calculate the TSS and IF after the ride but it would be nice to have it in real time if possible.

I just looked at my Garmin 500 tonight...similar question in mind. Follow this sequence to tell it your FTP:
Bike settings --> Bike profiles --> Power Zones --> FTP is the first line. You can enter your zones too, but it won't let you skip any wattages like the EN Zones are typically presented.
Hope that helps.
Yup. Make sure your FTP is accurate and the same across whatever platforms you're using: Garmin devices, WKO, Strava, etc
