How does the wind affect the measurement error?

In good conditions, the wind speed (1 m / s) is by a factor of 10 less than the speed (10 m / s). Thus, the measurement error is already substantially lower than generally assumed if the wind speed is not taken into account at all. With the parameter fit method, the average wind speed is also calculated in our method, which leads to a further reduction of the measurement error.

For an even more precise study of the influence of the wind on the measurement error, the wind has to be measured or modeled elaborately. The wind itself is always turbulent and depends on place and time and varies in all three dimensions. However, the average wind speed on the outward and return course is important for the measuring method; due to the turbulent wind the acceleration of the mass system (cyclist + bike) is low because of the high mass inertia. For the measuring accuracy the difference between average wind speed on the outward course to the average wind speed on the inbound course is decisive. This can, in turn, be fitted by a regression and thus the measurement error can be reduced to a degree.
