Within the time it takes to watch a Grand Prix, I came up with this solution:
Championship | 1st | 2nd | 3rd | 4th | 5th | 6th | 7th | 8th | 9th | 10th | Total |
Future FIA F2 championship | 60 | 50 | 40 | 30 | 20 | 10 | 8 | 6 | 4 | 2 | 200 |
IndyCar | 50 | 40 | 30 | 20 | 15 | 10 | 8 | 6 | 4 | 2 | 175 |
GP2 | 50 | 40 | 30 | 20 | 15 | 10 | 8 | 6 | 4 | 2 | 175 |
Formula Renault 3.5 | 40 | 30 | 20 | 15 | 10 | 8 | 6 | 4 | 2 | 0 | 135 |
World Endurance Championship (LMP1) | 40 | 30 | 20 | 15 | 10 | 8 | 6 | 4 | 2 | 0 | 135 |
FIA F3 European championship | 30 | 25 | 20 | 15 | 10 | 8 | 6 | 4 | 2 | 0 | 120 |
Japanese Super Formula (F2) | 35 | 25 | 15 | 10 | 8 | 6 | 4 | 2 | 0 | 0 | 105 |
GP3 | 30 | 20 | 15 | 10 | 8 | 6 | 4 | 2 | 0 | 0 | 95 |
DTM | 25 | 20 | 15 | 10 | 8 | 6 | 4 | 2 | 0 | 0 | 90 |
Indy Lights | 20 | 15 | 10 | 8 | 6 | 4 | 2 | 0 | 0 | 0 | 65 |
FIA WTCC/FIA Formula E | 20 | 15 | 10 | 8 | 6 | 4 | 2 | 0 | 0 | 0 | 65 |
National F3/Formula Renault 2.0 | 15 | 10 | 8 | 6 | 4 | 2 | 0 | 0 | 0 | 0 | 45 |
FIA F4 championships | 15 | 10 | 8 | 6 | 4 | 2 | 0 | 0 | 0 | 0 | 45 |
National F4/Formula Renault 1.6 etc. | 10 | 8 | 6 | 4 | 2 | 0 | 0 | 0 | 0 | 0 | 30 |
CIK-FIA World Karting Championships | 5 | 4 | 3 | 2 | 1 | 0 | 0 | 0 | 0 | 0 | 15 |
With this, I would change the system to an accumulative system over 5 years. Scoring 50 or 60 points in one year would grant you a 4 or 5 year exempt superlicence, but it would still be counted as 40 (which grants a 3 year licence).
