Watched a guy at the roaster in Louisville weigh his beans before and after grinding, lost 0.3 grams every time
Stood behind him at the counter while he ran the same 18 gram dose through his grinder twice. First pass came back at 17.7, second at 17.4. He said he's been logging this for two months and it always drops. Turns out the burrs are holding onto fine dust and he never once brushed them out between shots. A $6 brush from the hardware store fixed the whole thing. Anyone else track retention weight or am I the only one who started doing this after seeing it?

Dude at my local shop in Tampa did the same thing, weighed 20g going in and got 19.4 out every single pull. He was about to buy new burrs (like $200 ones) until I told him to just run some Grindz through it and see. Pulled the hopper off after and the chute was caked with old grounds, I mean a solid little wall of them. Took maybe five minutes with that brush that came with his machine and he was back to 19.9 out of 20. He bought me a beer for saving him the cash, which honestly was fair since I'd been watching him complain about it for weeks.
