“Hi Roy,
I wanted to give feedback that the 4-minute test for running and cycling was pretty accurate for me – also in relation to the Inscyd test results. Accurate to 2 seconds when running and 5 watts when cycling (other test days, mind you).
Since I had also completed your other tests in recent years, I was able to judge well that it went well together with this short as well as the longer running or cycling load, so that I only did the shorter tests this year.
Kind regards
Tilo Tschumi”
