How to read this table
A column holds the rows that carry the same name in the data. Two vendors can use one name for different things, or count it over a different period, so read both tool pages before you put two cells next to each other. A dash means that tool has no row with that name: it does not mean zero and it does not mean unlimited. A row that only one tool has is on its tool page. This page ranks nothing and picks no tool.
Each tool page has every limit row of that tool, the gotchas and the address of the vendor page that was read.
