- It is based on use of throttle, so using a different throttle profile, gives different results
Wait... what?
That's how SSDC did it, and has been a source of problems for us.
Why? Because different throttle, especially Scalextric OEM ones, have different throttle levels/curves inherent in their manufacture.
The result is that some controllers, even after calibration, will cause high fuel burn than others, because they produce a different throttle output level.
It also makes it too easy to "game" the system by using a different throttle curve.
If I use the H.Spd curve, I'll burn less fuel than if I use the L.spd curve, because the output speed is higher at lower throttle for H.spd. It might make the car harder to drive, but if I can handle it, I could run an entire race without refueling while the guys with linear or any other curve will burn MORE fuel (to get their car to go the same speed I am) due to their throttle being at a higher level.
This makes me sad, so I'm hoping that I'm misinterpreting your comment. I HOPE the fuel burn calculation is based on the speed level being sent to the car, so that regardless of the curve I like to use, it's the speed the car is being told to go that determines how much fuel is being used.
