Laughed at this because I did the exact same thing for like two years and felt like a genius until I had to trace a dead bedroom circuit at 9pm. Spent an hour flipping breakers one at a time while the homeowner watched me like I was the dumbest guy in Arizona. Turns out my "clean" panel was just a guessing game with extra steps. Now I label everything and eat the extra ten minutes up front. Saving time today usually means losing an hour next month.
