If you put the before and after graphs on the same plot, there is only one AT/IT figure used, so you can hide a difference that way.
Another way of tricking the dyno dynamics that doesnt show up on the graph is to strap the car slightly looser so that in use it climbs onto the front roller only and hence removes the power losses driving the rear one apparently.
