When the figure runs short

The conditions the maker names
Each figure is for the notch, bed, tile or joint the maker names beside it. An uneven surface, a larger notch or buttering the backs of the tiles takes more.
Waste
None of these figures adds anything for what is left in the bucket or spilt.
