I couldn't agree more:

Every gear decision I make is done with aerodynamics as an important consideration. It's very useful (and kinda fun) to see what the aero impacts are for various setups, as determined by field tests on my actual bike, so it's 100% relevant - no extrapolation from other types of tests conducted by other people required.
