Ted King’s average when he won DK in 2018 was 19.2mph. So you’re much closer to the published 1.8w than you are to the 2-5 watts. 1.8w would hardly register especially since the margin of error for your power meter might be 1%, so at 200w your margin of error would be…higher than your “watts savings” between the Gravon 420 and Gravon 250
Lol, they tested these things at 45kph…how long do people average almost 28mph during a 200 mile gravel race? That seems awfully fast in the dirt.
