Looks interesting! Cycling Aerodynamics Calculator | Rule 28 North America
Disappointed…was hoping this was requesting applications to be an aero tester for them. 
Yeah, I added a category and altered the title as “Tester” seems misleading compared to the tool and their own naming “calculator”.
Basically the Chung method for all
I like the notes: perform the test on a flat route and with minimal wind.
Clearly they’ve never ridden in the South West of the UK!
