It is interesting that no system changes the fact that Button wins, but 2nd-4th change quite a lot under the various systems. Kimi and Hamilton also swap 5th with the different systems.
I have it all as a spreadsheet with formulas, so I can quickly punch in any other systems that people want to try.
