US club class definition

So where is the official definition of Club class on the SSA site?

I downloaded the Handicap Excel file, and sorted it by any that had a "C" attribute in the notes. It appears to include LS-6 .898 to Austria SH-1 1.115 but probably in error it shows something i never heard of as Freedom Falcon with a HC of 1.550.
