Squee; I was thinking about doing that, but what effect would the truck type have? Depending on how people make their setups, materials used, cell-type, etc, weight can vary quite a bit for the same truck. Therefore, I would think weight alone would be more accurate since that's what the motor "sees" as the load.

Believe me, I'm not trying to shoot down your suggestion, I just need to able to do this programmatically and accurately.
