Sorry Ed, they are 1000cc times. 600cc times are approx 2.5 secs slower. Updated to be 14% (1:42.6 on a 1000cc). I'd expect B to be the most populated class.

D isn't a grade, under this proposal; it's just a brief stepping stone to getting race experience and a proper grade. This takes into account and caters for the other States that don't have 4 grades. I was thinking that we shouldn't get 'participation trophies', but having just been at the (very very well attended) presentation after St George with the sea of trophies being handed out to what looked like roughly half the attendees, I might have changed my opinion somewhat.
