Am I looking in the right place because the Flo Bikes recommendation seem to advise ~15psi difference for a 40lb difference (not 3)??

Enve site shows a 10psi (not 3) difference between 120lbs and 160lbs

MORE interesting is that Enve, like FFT calculator shows a ~16psi less recommended pressure for 130lb rider (like myself)… 25mm, 18-20 inner diameter (I have 25mm tires, rims 19mm inner ) —> ~27 on rim… Enve pressures actually agree with FFT, not Silca 😮!!
hmmm… someone’s got this very wrong! 🤔
the Flo chart doesn’t take into account impedance so you can safely ignore that one!
