We tested 20 different probe positions and most of them with all four athlete positions. We originaly wanted to derive a calibration function as well, but since we want the measurement for help in bike fitting we didnt like that the measured dynamic pressure itself was position dependent we now measure air density once per pedal revolution and adjust accordingly.Why are you measuring dynamic pressure? To ensure inter-run repeatability? To calculate exact CdA values? To derive yaw and be able to do yaw sweeps with field tests?
I don't really see how an adjustment of air density can solve blockage effects. Adjusting density you just get a more accurate value of the relative velocities seen by the sensor
