What grade is it?

Grades of routes are an endless source of argument and debate. To add fuel to the fire we have produced the following table (taken from a tee shirt). What French grade is it? What grade would it be in the States, do you understand UIAA grades (do you care?) The following table is from my own experience and comments (not rude), revisions, additions are welcome.
