Ah yes good pick-up @KoAStR . I'm using the tables to improve my rather poor skills in Excel and sometimes the formulas does not work as they should . This time a reference to column "M" should have been to column "N". See the update below.
As for how the index work, 0% is the expected dividing line between server 1 and 2. Drivers in division 1 should have qualifying performances in the negative while division 2 should have positive values. The % is the difference between a drivers lap and the expected middle lap.
