One of the issues with HrTSS is the baseline of 20/hour. This would say that laying around all day is 480 TSS. TSS accumulation is skewed higher for easier efforts relative to what the real load feels like. 2 hours on the couch gets you 40 TSS, 2 hrs of easy L1 training gets you 80 TSS and at least for me, 2 hrs of 60 TSS/Hr level effort =120 seems a lot harder than L1 + 50%. I think it would be more representative of aggregate training load if the default baseline of 20/hr was not there.
