IMO, field testing equipment for small changes in CdA is hard to do and subject to inaccuracies. If you test on different days, Rho (air density) will be different. The fastest conditions are low air pressure, high temperature and high humidity. I use the indoor track at Carson and hire ERO to use their program, equipment and sensors. ERO measures Rho at the time of the test.
