How many rows fit a bed and the spacing that results.
Subtracting border margins leaves usable width, which is divided by the plant's smallest comfortable spacing. Even row spacing keeps pathways wide enough to work in while using the bed area instead of wasting it.
Row Spacing
Usable = bed width - 2 x border; rows = usable / plant width
