This might just be a design flaw, but the x0 quantity indication at excavation sites are really quite meaningless. They never go above 0 and when you do complete the excavation, they are gone.
I recommend changing this to the progress complete so you don’t have to open a window to see this data, and when it is excavated, change it to indicate how much stone there is to be harvested. The symbol would have to change to stone as well.
