Just a suggestion for 1/8th EP,
When it is held at these big meets, like nsw titles etc, we could make it just one final of 10 minutes and if there is more than 15 enties, we could go for a,b,c finals, no bump ups, just one final each, no semi finals etc.
Also the EP final could be done last race on the saturday, that way we would not have the problem of having 3 EP finals and juggling the marshals around to fill in the marshall spots as we have at the recent events.
