Yeah kind of. People in googletube comments went wild for this too. However, depending on the filter paper you use, the brewer (more ridges, more bypass, less sticking grinds), the beans you are using (some produce more fines than others), how many fines your grinder is putting out, and how aggressively you are pouring, you can really have your cone look at lot like all three of these even on the same grinder setting - the line can be especially blurry between the first two. I’m not saying this isn’t a useful picture, but I wouldn’t necessarily sweat making the middle one your end goal. While it’s great to try to troubleshoot mid brew - if you still end up with a bit of a rough cup, I’m shamelessly plugging my coffee rescue article as a way to salvage it to drinkability.
