speedway was better attended before sky! that's answred you........sky always felt it had to explain the rules 10 yrs on, they don't do that with darts, tennis etc,,
the constant crazy rules speedway shoots itself in foot with don't help/guests..(poole had 4 guests and r/r one night)!..
promotions that really tried, did keep attendances reasonable, and I know commentators have to make a bad game seem interesting,
but viewers are not daft..
