maaaaaaan , i don't think any lab test can translate to real world performance , contact patch smontact patch , you will always have a varable that counters the point you are trying to make , it can go on and on , solve two variables , and 3 more pop up .
heavier weaker rider , vs lighter stronger rider , bumpy jagged road vs perfectly smooth wood track , there is no end .
loose watts in the tires make it up int he muscles , loose strength in the muscles , make it up in aero gains, use a tubeless tire on a basic wheel to get a boost , or use a standard clincher on a high end wheel to get a boost , on and on !!!!
