Hi all! Was wondering if anyone has a checklist on how to optimize quality of data collection when doing coast-down aero testing?
I have done a bit of Chung testing previously, but the only working U-shaped section of road I have found is about an hour away, whereas I have a straight 1km road with 5% elevation just a few minutes away. Would do simple A-B testing of helmets, bottle placement, mantis elevation% (5-10-15 etc), shoe/cleat combinations etc. Maybe along the road try different combinations of setups, but it quickly gets complex...
I would simply compare max speed at the end of the hill, running like AABBAB between two options. Absolute cda is not an issue. So I would need to control for these factors (changes for the duration of the test) what else? Thankful for any insight
Temperature (colder is better as aero factor more prevalent?)
Humidity
Total weight
Wind, strength/direction (looking for no-wind days)
Tire pressure (digital pressure meter)
Dry road
Speed/cadence sensor (not gps)
Repeatable position
Holding a straight line
