scunny delight

I have had a look at the results on the Plymouth website and quite frankly I dont understand the format one little bit. Two riders were missing, yet apart from heat 12 all heats had 4 riders in, but the strangest thing was the fact that some riders appear to have had 5 rides whilst others only four, whats that all about. Congratulations to the winner though, four straight wins in the heats and then 1st in the Final. Would have been a shame if he hadnt won. Top scorer after 5 rides each is a much fairer way to score though IMO
