Fun side story -- I bought a food scale back in 2010 when I got really serious into prepping. Hadn't used it for a few years (one of those things where you get to a point of eyeballing pretty well when you eat the same thing for enough years), but wanted to really dial it in for a bit, so I busted it out and was weighing some chicken. Seemed like I wasn't getting very much, but whatever. Then after 2 days I was like, hmmm, so I found a 10g weight I had for recalibrating my tiny micro scale that I use for supps, put it on there and it shows up saying 30g LOL. I tried resetting it and everything, but that stupid scale is just done for. And it's showing 3x off (I tested it on a couple other things and it proved to be consistent in its inaccuracy).
So for 2 days I ate WAY less protein than I'd intended...smh
