I have noticed a discrepancy in the 6 week average and daily average TSS as displayed on the browser on my phone and laptop. I have looked through recent weeks and have not found a week with a difference in actual TSS. Here are some examples.

I’m not to fussed about the difference, but am curious about what might be causing it. FWIW, I only noticed because I super excited about TR pushing workouts to Zwift and plan on following a TR plan for the first time in several years.
