That line about running your tag line by hand for 11 years is the whole thing right there. We all got some habit we picked up from a guy who trained us, and it just becomes law in our heads until somebody stops us cold. What gets me is how often the wrong way works fine for years, which is exactly why nobody ever questions it. Then one day it matters, and you find out the hard way that doing it wrong a thousand times doesn't make it right.

Our club had that exact guy for two years, always pushed the 800 pagers and quit around chapter 3. We started having everyone give a quick "where I'm at" before we dig in and it killed all the awkwardness. Now we just laugh about it and move on.

What was the glitch that got you? I ask because mine just did something similar on a hallway width last month, software said 3'6" and my laser read 3'4" after framing. Turned out I'd snapped to a wall face instead of the framing layer, took me 20 minutes to catch it and I never would have noticed on paper because I'd have just measured twice with the tape. Sketching by hand had its own traps though, like when you scale something wrong and the whole plan is off by a foot and you don't find out till the client walks the lot. So maybe the real question is which mistakes are easier to catch, the ones you make with your hands or the ones the computer makes for you.
