Hi,
it seems to me that the Equation 6-11 (Fitness Equipment Device Profile, Rev 4.1) of the Wind Resistance is wrong.
First, it's not very clear the unit of measure of the Relative Speed. In fact, the Wind Speed is measured in Km/h and there is no reference for the unit of measure of Bicycle Speed.
So, if the Relative Speed is measured in m/s then the Wind Resistance formula should not divide the Relative speed by 3.6.
If the Relative Speed is measured in km/h then first part of the 6-11 equation should be fixed.

It has been about 10 years of this post and yet, there is no answer for it.
IT's true what the post is saying. the documentation is wrong.
also in the documentaion the gravitational resistance is not clear likewise.
for example there is track resistance that we give a grade (slop) and it calculated gravitational resistance.
the process is like there is claculation formula for interpreting the slop (with offset of 200%) and then the
gravitational force is calculated based this formula : Total mass * g * Grade/100.
Again not clear what Grade here is . is it like 200%, then : total mass * g * 200/100% => total mass * g * 2%.
it doesn't seem correct.
I am wondering how a documentation is not corrected after 10 years.
how the support is so weak, and how the C++ code given for hearratte etc. is so uncomprehensible.
Thanks.
