That is a great idea! This is exactly why I visit these forums. Very inexpensive way to achieve zero retention!

I just tap the top with my palm to form a seal.

Where did you find this?

I found mine at a local dollar store when I was trying to find something that would allow me to remove my spent coffee from filter basket without the need of knocking/damaging the puck.

Not athetically pleasing but a handy place to put it when not in use

If there are a few grams stuck around the base of the burrs that do not get displaced, once that is filled, you will have zero retention every grind. (Without blowing grinds out from the corners after every grind).

To put it another way:
If the Monolith was in the middle of the forest, ground some coffee, and no one opened it up to look, would there be any retention? I think not.

This assumes that the forces which put the grounds there in the first place don't dislodge them?
It seems to be contradicted by my and other's experience with other grinders when sometimes we get more out than put in.

same here. Thats why daily I place the nozel of a shop minivac directly against the opening of the magnetic funnel, wrap my fingers around it to make a good seal, then turn grinder motor on and pulse suction thru by placing my other hand on top of the coffee bean entry funnel then off. With this technique I add 18.7 grams to get 18.0 grams out.

Has anyone here experienced unstable results in terms of retention? I've noticed from time to time, I would get a few grinds that would result in ~0.5 grams retention while other times I would get less than 0.1 grams. While I understand RDT is suggested for the least amount of retention, I haven't been using any RDT or cupping the funnel because while looking at Denis' "tutorial" video, he does not do any of this (and I'm hoping to lessen the steps). Also, in his grinder test report, it indicates that he does not use RDT.

FYI, the grinder probably has just shy of 10lbs put through (so probably not fully broken in) and I haven't removed the chamber to clean since after the first week of receiving the grinder (after grinding ~0.5lbs of beans). Beans are generally not oily and either light or medium roasts. The burrs are the upgraded DLC and since receiving the grinder, I'm about 2 to 2.5 numbers finer in my grind adjustment.

Variations in humidity would affect the amount of static electricity generated by the grinding.

And also different beans and even same beans with different roast.
