I should correct myself, measuring the amount of coffee in is definitely important! Be it through a calibrated timer on a grinder or done by weight. I meant using scales to observe the grams of coffee out isn’t necessary with a bit of experience. Again, it can help, but I wouldn’t say it’s something necessary.
Ah I see, my bad! I'd say measuring/timing the output is handy to get you in the right ball park when dialling in a very different set up. But yeah, once you're in the ball park doing it by taste is your best bet IMO (though I still monitor shot times just to ensure consistency).
