Beyond that I think you get into (controlled) tests that could potentialy damage the cells.

I agree that this would produce a very "controlled" test, but it's also what you usually see in the graphs that manufacturers produce. (And at that - probably from a brand new cell that is in it's best condition) In general none of our buggies are going to run at over 20A continuous and they really high amp draws will be seen during hard accelerations and at top speeds. It's important to me how the Amp draws at top speed effect voltage drops as that's where you'll feel the most impact.
I kinda like this testing comparison as it's showing what these cells will be doing after being run for a while - a little more real-world.
