GARMIN CONNECT INFLATED TSS

ive been on two rides now, first with just edge 830 and second recording on both F5+ and edge 830.

first ride just edge 830 displayed 216tss on unit, when uploaded to GC it displays a tss of 270!!!

second ride both devices, tss of exactly 107 on both devices, when uploaded to GC on both identical workouts it displays a tss of 147!!!

i have checked and doubled checked my FTP on both devices as well as re-enter it to both devices as well as check the FTP in the GC app and re-entered it and saved and synced.

the problem is the GC app or website calculating the tss incorrectly. It’s not even the IF because that is correct.

this is very frustrating! Im trying to follow GC software more nowadays with the physioup feature but if it’s not accurate I will revert to TP as TP seems to record the right figures
