Would engine load be a reliable indicator of drag?

Wouldn't you want to testing drag and downforce at the same time if your goal is FE. One can certainly create downforce at the cost of drag.
If all variables could be fixed as constants, and drag was the only variable in the system, then throttle position could represent an aerodynamic change in load.
The rigid SAE protocol for coastdown testing might serve as a template for an accurate accounting of all these associated,potential variables. It's quite demanding, such so, that I'll not attempt it anymore.
