do you think I should make a new thread?

Yes, then we can ask questions about how to mitigate the flaws. I still think the best test is a road on a hill in the middle of NOWHERE followed by a long flat interval. That way you can coast to the bottom gaining speed and then coast to a stop. Multiple runs in mode X will yield an error factor that you can take into account on subsequent runs in mode Y.
