Can I put in my 2 cents for ZRS score for entry to races should be your highest score in the last 30 days?
If you get moved up a category you should stay there for 30 days and not be able to drop back down the next day by tanking your next race. Anti-tanking is also stupidly easy to beat. I’m sure all the racing clubs/facebook pages know the formula by now.
But anti-tanking is a hard nut to crack which is exactly why you need to use the highest ZRS in the last 30 days as the race entry requirement.
