I agree with the majority here and Gian, in that 2 tyre leagues do, on average, tend to have closer race results, than leagues that do not have this rule in place.
I am though curious why there is a 20 laps Hard tyre start for non set ups in Elite in the league though Nathaniel. Does it take into account the possibility that someone may have had to miss the race to attend to an emergency hospital appointment for themselves or a relative? It seems like a double penalty, when already in truly competitive leagues, a non set up is guaranteed 0 pts.
The league rankings, whilst I commend the effort that has gone in, as others have pointed out, are flawed, with only the competitiveness measured and not the strength of the league.
For example, a very similar group of F3 racers may produce very similar race results all season, leading to close final standings, and indeed qualifying for the competitive criteria. But if the top F3 racer were to race in a true top tier league, they would only finish around 8th each race.
As such, as the league rankings do not measure the league strength, but give off the impression as such with a numbered tiered list, it will only cause grievances with managers and hosts, who are not on the list.
Whether such a list and measure, that can cause grievances and allegations of bullying, especially with managers and hosts who are on the autistic spectrum or similar, should be pinned up on the league board is another debate.
There not a non-set-up penalty, the penalty if you don't follow the handicap system. Anyway, with my disabilities and Autism, I now realize it a non-official leaderboard. Gian continues what you're doing but IGP really should take over or remove the leaderbord.
