Listener Crossword: Statistics

Solver Numbers

The columns 0-10 list the numbers of solvers with that number of submissions missing or in error in the year. The “Total” column gives the total of those; the “Solvers” column gives the number of different solvers who made at least one submission in the year (when known).
