For instance if your load correction is lets say 0.2 and you are using mapped points 3 and 4, with 3 being 40% and 4 being 60% i would multiply that .2 * .4 and .2 * .6, then apply the weighted correction into each mapped point. Generally I do a flat cut off somewhere around 20% where I stop weighting (ie: if its 82% and 18% I'd do the entire correction to the mapped point at 82%).

Theoretically this method has inaccuracy in it, after all your entire error could be coming from mapped point 3 while mapped point 4 is dead on... but that's going to be pretty uncommon because in that case mapped point 3 would have to be off by a larger margin. This isn't necessarily a hard and fast rule, and you can play around with the numbers as you see fit. For instance if your values are always dead on until mapped point 3 is activated you could do the same weighted correction, but only apply it to mapped point 3 assuming the entire error is in that mapped point. If you wanted to attempt a 'one shot' fix then you'd have to multiply your correction factor by the inverse so that when it is only weighted 40% it applies the appropriate correction, but doing such a drastic change could cause you to overshoot and chase around a bouncing number.

Hopefully this helps some and good luck getting it nailed down, thanks for posting your progress so far for others to learn off of.
