I've helped a few friends learn the ropes and they were pulling good shots in 20 minutes with the aid of very precise instructions. What took them more time was diagnosing extraction problems and diagnosing taste defects took even longer.
This thread "scale vs. no scale" falls into the mechanical learning phase. Newbies certainly benefit from eliminating a significant variable like dosage; for them, investing in a $15 scale is a no-brainer. For the more practiced, it's more a matter of preference than necessity.
Dan-my-man, you correctly identify the issue at play. I submit that most people just want to find a simple and "automatic" way to pull good shots time after time. You and I both know that being able to do that is as much a matter of experience as it is of having a rote technique, yet I'd be willing to bet that you (like me) use a rote method 95 or more percent of the time, if only because it is brainless and easy to do so.
Like anyone else here reading this, who has the scars to prove it, I have had many trying experiences over time in trying to make espresso. I remember vividly the several times when I pulled 5 (or was it 7?) consecutive sink shots and could not figure out why the technique that seemed to normally work for me failed to work in a particular instance. In the last several years the worst it has ever been for me has been maybe 2 or 3 sink shots when changing over a grinder from a coffee that needed a very fine grind to a coarse one, or vice versa. Even then it was pretty much brainless.
Once you get to the point of making brainless espresso, you can change your rote technique on the fly to adapt to a particular circumstance, without giving your "adaptation" very much thought, either. Again, this all comes from the experience of doing it many ways and many times. I'll give a couple of examples from my own technique, which by rote now involves weighing coffee into a ramekin on a gram scale and using the same dose each time. But what if the coffee is near its end in the grinder and the resulting grind will therefore be coarser for that last shot? I just put an extra gram or gram and a half in the PF and the shot comes out ok. Or what if I got a substandard shot (needing a grinder adjustment) and then forgot to adjust the grinder the next time around, more or less guaranteeing another mediocre shot? On the fly you can just increase or reduce the dose to account for that, and you can probably get a decent shot, rather than tossing that coffee and grinding again. These things you learn by doing and you can learn them well enough that they become automatic as well, basically like an appendage on your rote technique.
But you don't get to the point of making brainless espresso without having pulled a whole lot of shots under a whole lot of different conditions over a long period of time, regardless of whatever mechanical method of espresso shot making you have decided to use.
