If I had to make up the rules for this league I would do something like the following:
- 15 teams should give plenty of scope for 5 or 6 levels of performance within the field. Say have 2 teams with no restrictions and 2 teams at the bottom with cars 2.5 to 3s slower and the rest spread in between. Mix things up in mid-grid so a team may have less engine restriction but more ballast than another.
- At the end of each season each team is ranked 1 to 15. Team 1 has first choice on their car for the next season. New teams that replace ones leaving, or teams running two new drivers, pick last.
- Team ranking could be made up of the constructors table, with teams who score no points sorted by their best finish position, or instead there could be a handicap ranking. Something like an average finishing position (with retirements being ranked by distance covered and no shows given last place) with a performance related deduction. Best teams have no deduction, but say the lowest ranked team gets a deduction of 30% with the rest spread in between. Their average finishing position could be 12 then minus 30% gives 8.4. The handicap deduction would have to be fairly gentle and properly balanced because slower teams will always outperform their expected finish by finishing ahead of retirements and no shows.
Using this system a team and driver could win their championships but still lose the best car for next season and would really have to prove their mettle.
