When one visits a PrimeGrid (PG) webpage, the add-on detects if it contains a table list of tasks status and if so, it calculates the % of those that are "Completed, waiting for validation" or "Completed (1st)" and appends the result to the table.
For the add-on to work properly, Primegrid must have been set to use the English language (https://www.primegrid.com/language_select.php).
