Working more on these calculations. I am including two efficiency/percentage baselines, one for the decarb method and other for the media (butter, oil etc) My thoughts on decarb are cookie sheet, MBM carb box at 60%. For butter I am continuing with 75% for now. So I start off with cannabis weight and percentage of thc and that gives me a gross weight in mg of THC. Decarb via cookie sheet reduces it to 60% of the gross. Then the media again reduces, so in this case butter brings it down to 75% of the adjusted decarb total and then divides that across the gross media that was added to make the infusion.
Right now I get about 50% of my media returned. So if I start with a 4 cup (gross volume/weight) infusion I end up with 2 cups finished media returned. Really inefficient.
