So what actually changed for you between the scale days and the scoop days? I ask because I went through the same thing and the real question isn't grams vs scoops, it's whether your beans changed too. When I was weighing every dose I was also buying from a local roaster every week, and once I started grabbing the big bag from the store to save money, that mattered way more than 18.0 vs 18.4 grams ever did. The scale mostly matters when you switch beans a lot, because scoop size changes with how the beans sit in the bag and how dark they're roasted, so you can drift a couple grams without knowing it. If you're drinking the same beans every week, your tongue learns the taste and your scoop probably lands close enough anyway, so the 30 seconds might just be buying you peace of mind, which honestly is still worth something.

My mom had a $6 can opener from IKEA that lasted 12 years. Read somewhere that the cheap ones use soft metal gears and they just strip out. Bought a $20 one after my third dead opener and it's still going.
