The comment on the crit thing, I think if the field is too large they should split the classification's race time into two 15 minute heats and a 7 minute finale' after a fair cooling period.
that’s a death rattle moment for the sport. Promoters have a nearly impossible time making money. No one is going to pay “make the promoter money” freight on a 15 minute race chance to advance. It’s not even worth driving to that. I’d get a better workout hitting myself in the head with a hammer.
