Target Loading a trailer, and calculating adjustments

[Hammerhead]

So how do we use this information to adjust a load we loaded wrong?
Let's say we loaded a 46500lbs load with the above unit, but we missed our Target and the shipper will only move the load once, and we have very little room to play with.
Let's say we ended up at
11900
32500
35100
So we need to move a minimum of 1100lbs forward, but not more than 1500.
To balance, our Target should be 1300 lbs.

Our load weighs 46500 and we need to move 1300 of that so:
1300/46500=0.02796 or 2.8%
Our trailer w/b is 41' or 492"
So we need to move the load 2.8% of the wheelbase
492*0.028=13.77"
So we're going to move the load 13-3/4" ahead to reach our goal of 33800 each tandem group.
