The matrix is designed to give you a general idea how you did in each section (fail/pass/killed-it).  It is not designed (and therefore does a terrible job) in showing you how you did overall.
I made up a spreadsheet that calculates people’s min and max possible scores for all the L2 matrices posted on AF.  The average range between min and max possible scores is 23%.  That is, in general, two people could have the same matrix although one of them got 60% (fail) and the other 83% (easily passed).  There was one person (whatsyourgovt) that has a min possible score of 50% and a max possible score of 80% (this person failed).  While there is another person (lankylint) that has a min possible score of 49% and a max possible score of 74% (this person passed).
Don’t read too much into the matrix.  Some look terrible but are still consistent with a high max possible score - while others look great but are still consistent with a low minimum score.
