Funny how this works the same with physical clutter too. My garage was a mess where nothing functioned until I sorted tools into clear bins. That layer trick you used is just digital organization for the same problem. Why do we always try to work through the visual noise first instead of fixing the system?

Wait, roman coins in iron age layers? That must have made your brain hurt trying to figure it out. I can just picture the total confusion on site before someone finally checked the stakes. @val_craig is totally right, triple-checking is the only way. Having to re-measure everything overnight with a borrowed laser sounds like a special kind of torture. That's a solid lesson learned the very hard way.
