Think your maths is a bit wrong.
Going by Speedway Updates (Ignoring heat 15)
the Ippo top-scorers should have been: King 10+1, Brennan 10, Ellis 8+2, and a toss of a coin between Doyle 8+1 and Sayfutdinov 8+1.
Brum should have been: Jepsen Jensen 9, Jeppesen 5+1, Rew 5, Vuolas 2+1
So it looks like the pay rates couldn't have been too good as Doyle, Sayfutdinov, Jesper Jensen, Jeppesen and Rew all ducked it.
Fair play to Thompson, Musielak, Hume and Edwards for taking part. I'd say it reflects worse on Doyle and Sayfutdinov for ducking out as it's their home club.
