Real range vs. declared range?

Dunno if there are any "grin" fanboys on this list here but the grin "cycle analyst" gives you a lot of quality info. I think i've only scratched the surface of what mine can do. In-the-moment speed and power read-outs, and it will tell you the watt-hours left, and calculate the honest watt-hours of the battery itself (nice way of testing manufacturer specs).
Is it this? https://www.evworks.com.au/grin-technologies-cycle-analyst-version-3-power-me. I didn't know about! Interesting...
I feel like a decent understanding of the drag coefficient could just be to cruise on flat and record watts at differrent velocities, and extrapolate the coefficient.
How do you know how much power you need to cruise at a certain velocity if you have no throttle?
