The technical term for that, is "massaging" the load.
I had a company chairman at a panel one time, flip out because I accused the
local management of doing just that. He couldn't believe that I had the audacity
to accuse the company of being dishonest.
Uh, Mr. Chairman;
"If you will look at the next exhibit in my case, there are 3 notarized statements
from the pre-loaders that witnessed it."
Moral of the story....
Be kind, and communicate with your pre-loader.
