Heard a podcast a few days ago that basically said the same thing, how our brains trick us into thinking the same patterns are brand new. The host was a psychologist and she talked about something called "routine blindness" or whatever. Apparently it happens when your brain gets so used to the daily grind that it stops actually processing small differences. Makes sense though, I catch myself zoning out during meetings and then realizing I've heard the exact same complaints before.

The break in period is real but honestly I think most of it is the user figuring out the grinder not the grinder itself. I spent a week making terrible coffee before I realized I was cranking it to the finest setting because it felt more "precise" or whatever. Ended up with a cup that tasted like someone yelled at the beans through a megaphone. @paul_lane80 your buddy Tom's story about the scale hits close to home, I still use a measuring spoon like a caveman and just pray the ratios work out. Maybe I need to accept that coffee involves math and stop pretending I can eyeball it.
