The one time he broke his own method
- Learning as you go isn't the method — 'This isn't the normal way I do it, this isn't the way I recommend anyone doing it.'v2643
- The judgment call was scale — It was the guest house, scanned right after the main house on the same property.v2643
- Prep plus scan can run half an hour — He wasn't going to spend that on a second structure that didn't warrant it.v2643
Prep-then-scan stays the method; this is a documented exception, not a shortcut to copy.
