Great dialogue and discussion. This is awesome to see!
If I may, I'll add my own thoughts:
If we can assume the old PAX system was broken, (given that the top placing positions were dominated by cars classed SGT2 or higher) I think it's fair to say that the latest PAX system to rectify the issue may have swung the pendulum a little too far in the opposite direction, given that SGT2 and higher classed cars now occupy the majority of the bottom half positions.
While we can certainly do more scientific calculations to prove this, a simple look at event standings after the PAX multiplier has been applied (old PAX vs newer PAX) would support this position.
Now I'm not suggesting by any stretch, that this was done with intent. It was merely an attempt to correct an old system and ensure all classes had a more competitive chance.
However, now that we have more data available, we can see that refining the PAX multiplier factor could achieve a more balanced result and can further level the playing field for all, without diving full-on into a whole new classification or rule set.
It will never be perfect, but it can get closer regardless of which direction the club decides to go. For the record, I am not opposed to either.
