I thought tss was calculated from power values, it was just the only ride where GC gave it a value was the one when I wore an HRM. Will have to have another tinker with GC when I get home tonight.
That shouldn't be the case. If there is power data there should be a TSS. Are you sure you are looking at the right metric? Has it read in the power data? Check that tab that has the raw data and see if there is a power column
