[QUOTE=freonjoe;75051]Do you know how many Kg's you're averaging per cat?[/QUOTE

If the cat has full combs they average 3 lbs., the comb is hygroscopic and absorbs a certain amount of free atmospheric moisture. The powder on a wet day has a cling to it but not enough to clump, on dry days the powder flows though the funnel freely into the drum while on wet days I have to give it a shake.

Any moisture content is going to add unwanted weight, water weighs 9.9 lbs to the gallon. So it will be no surprise when the refinery makes adjustments for moisture.
