Question for GiveusaB. You say do away with the "Demo" races, do they take place before the advertised start time or after it? If before what time would be saved?
We had the same at Glasgow, three rider at the gate red lights flashing, riders returned to the pits and were immediatley put on two minutes. Race went off with three riders, no information.
