Not complaining at all about the sensitivity. It's different than the conical and it's a learned skill to adjust to it. It also may be different between machines, don't know. I always sink the first shot anyway and have learned from the first one how to adjust the next one. Sometimes get the Conical and Flat confused and with the the grind setting opposite on each one I have to watch what I'm doing.

I always write on the label the dose, grind setting and the rpm that I used and as the coffee ages small adjustments may be needed.

interesting, i've noticed that lower rpm's have given me much better extractions. channeling as almost become a non-issue and getting better body and mouthfeel in the cup.

The grind setting is very sensitive- meaning small adjustments make a big difference. I can notice a one mm change in shot time. This is just the nature of the beast of a large flat burr grinder. This is why people find that conical grinders are more forgiving: they produce more equal fines across a wide range of grind settings and the flats do not. I cannot tell you scientifically why that is, but I can see how it plays out with my two grinders side by side.

Is it really the flat burr grinders or is it just a aspect of grinder design? Where a small movement of the grind adjustment causes a significant change in grind fineness or coarsenes (and therefore a large difference in shot flow /time).

I dont believe this is always the case. As with EG1 i saw it mentioned where each stepped notch is an extremely small burr movement.
I have the mahlkonig peak and it goes from 1 to 10. with each marking broken into 10. So 1.1, 1.2, 1.3 ... to 2 etc
Once dialed in, i find that each marking means about 1 sec (so not very much).

If a small movement in the grind adjustment causes a large difference in shot time/ flow, i would think this would present an extra challenge to dial in. Because the difference between a gusher, ideal shot time, and choked shot is very small. So to get in range i would think might be more challenging , than to fine tune 2 sec slower or faster etc.
Also to get back to a certain setting when using multiple beans i would think could be more difficult.

It is really pretty easy to dial in. My comparison was the monolith conical which is ridiculously easy to dial in. As far as I am concerned there are no flaws in the monolith flat adjustment system/ procedure.

If a flat burr and a conical burr grinder have the same thread pitch on the adjuster, I would expect the conical to change grind size around 1/2 to 3/4 as much for each degree of adjuster rotation as the flat would, because the tilted orientation of the conical burrs relative to the adjustment axis. Of course, flow rate depends on fines generation as well so it's probably not a simple relationship.

That's my experience as well.
