I think you are recalling the World Pairs which used 6 rider races for a few years until 1990 when there was a serious injury to Piotr Swist in a semi and another major crash in the final. https://en.m.wikipedia.org/wiki/1990_Speedway_World_Pairs_Championship#:~:text=The 1990 Speedway World Pairs,and the less fancied Australia.

But it clearly Isn't. Clean Sports do an excellent job.

I was wrong, it was SIX (yes six!!) times 4 August 2016 George Piper (IoW) v Bradley Andrews (Cradley) Piper took seven rides after fellow reserve Tyler Govier withdrew following a ht 2 fall. With Andrews on song and getting extra rides the pair met in heats: 2,4,8, 11,12 and 14. Andrews beat Piper 4-2 which was crucial as Heathens won the match 45-44.

I'm pretty sure I've seen two reserves race each other 5 times at the Isle of Wight.

Not sure the Govt. has made it up to this Wednesday... and that was yesterday

I'm assuming this will be behind closed doors, but with just 6 days to go surely it is time to make that official. Weather forecast looks a bit dicey.

The problem with using empirical data is that you need to tease out the differences between variances that are due to random chance and those attributable to actual biases. For example if Roger Rabbit who somehow fluked his way into the GP series and came last in every round had draw numbers 2,3 & 4 in most rounds then to what extent is his poor performance caused by being in those positions vs. the extent to which the scores from those numbers are adversely effected by the frequency with which Rabbit appeared in those positions. (see for example http://blog.philbirnbaum.com/2011/08/tango-method-of-regression-to-mean-kind.html in the context of baseball) The question is does 152 GPs give us a large enough sample to remove the affect of random chance? It seems quite possible that all but the most egregious of variances will be due to chance. Some things do stand out from this analysis, notably the huge advantage offered by gate 1 in heat 1 and that you don't want to be in yellow after a track grade. I wonder to what extent biases in gates are damped by overtakes - table 11 suggests a strong correlation between number of passes and the variances shown in that table with Krsko and Prague having much higher variances than Malilla. Interesting to see the input from Phil Morris too. Anyway I do love a good discussion on Steiner systems (I first encountered them when doing my Oxbridge entrance exam, and immediately saw I was dealing with the 20 heat individual speedway race format).

And now the season is over (bar a couple of loose ends) thank you for accompanying us on what has been a very unusual speedway journey.

It's irrational too. In a 3 all whether you get a bonus can depend on whether the rider at the back coasts over the line or pulls of the track a few metres from thd finish.

Yes no bonus point if it's a 3 all with 3 finishers or a 5- nil

Rookie error from Dave Goddard, Sayfutdinov did not get a paid maximum. He didn't get a bonus point in heat 11.

Well you have your answer!!

And hearty congratulations are due, as she did it again in her second ride!
