The Thirteen Heat Formula worked well for years.
Then they changed it - and we lost our Second Halves. They changed it and we lost TWO Races. (If I remember correctly there were 4 Races in the Second Half). TWO Races added in the Fifteen Heat Formula and FOUR Heats dropped from the Second Halves equals a deficit of TWO Heats of Racing.
As you say - MARVELLOUS!!!
Oh, and British Speedway went in to decline didn't it - because there were no Second Halves for the youngsters to get in some meaningful Racing Practice. The decline in youngsters riding Speedway is due, at least in part, to the dropping of the Second Halves.
Old argument - yes it is. That doesn't change the fact that it is correct though - does it?
As you say MARVELLOUS!!!
