Not sure I understand what you are trying to say...sorry.
The point of the race gas test is to prove that the car CAN run knock free IF the maximum timing values are set properly, (ie low enough) to prevent the knock sensor from detecting events an thus having to drop timing.
With increased load, timing table maximums need to be dropped relative to stock values in order to prevent timig drops based on knock sensor detection events.
