Spoiler, its RDT
In case people do nto know what RDT is, which they really should if they have been into coffee for a little while as it makes a big difference:
RDT is Ross Droplet Technique, which is very much adding water to beans. Named after David Ross who came up with it back in 2005
That’s the trouble, it didn’t get vaporized or vanish. It’s still in the grinder, or sticking to the collection bin. I’m not an expert or anything but I suspect that the residue oxidizing and mixing with the next batch will have more flavor impact than being a little off with your measurement.
This feels like it would have the biggest effect. Nice thinkin!
