The Green Sheet Rolling Averages have been based on 20 matches for a while, but this season (2022), the number of matches is reducing by 2 each month, so: June 18, July 16, August 14, September 12, and by October the Rolling Averages will be based on the last 10 matches.

Obviously, the smaller the sample, the bigger the impact on the overall average - especially when a new score is added and the oldest is dropped.

IronScorpion Posted May 13, 2022 Report Share Posted May 13, 2022 This, as you say, could be biased either way(Home or Away) but it could slightly eliminate average manipulation for the following season if riders, in their respective teams, are already in the play offs. It might be a bit strange but most of the meetings in September & October will be Play Off or KO meetings which do not go towards your CMA's. My personal view on this is ALL types of meetings count but in 20 meetings, drop your lowest 4 scores as the PL only has 6 teams meaning 20 league meetings if the riders ride in all of them, similarly, in the CL 11 teams meaning, again, 20 league meetings if ridden in all.

Sings4Speedway Posted May 14, 2022 Report Share Posted May 14, 2022 I can only see manipulation on the rise. Teams whos play-off chances have gone will see riders tripping over themselves to finish last. Two "bad" matches could easily see a rider trim 1-2 points off thier average. 4 Quote Link to comment Share on other sites More sharing options...

Exactly, which is why I would take off a couple of low scores from the "cheaters". Quote Link to comment Share on other sites More sharing options...

This once again leads to more watering down of the product by naturally forcing everybody’s average higher. I don’t believe that’s a good idea and I don’t believe that average manipulation come the end of the season is actually that much of an issue - especially in todays market where there is a shortage of riders. I don’t think 10 meetings is a bad thing either as that represents half a season - however it should include any conbo of 4H/6A, 6H/4A or 5H/5A to prevent lop sided averages.

Tbf, you could just increase the points limit accordingly. While I can understand the logic used for the rolling averages within a season (phased reduction of number of meetings), I would think for the following season using the last 20 (10/10) would be better. The more meetings, the more you dilute the impact of any thrown points. Quote Link to comment Share on other sites More sharing options...

Didn't it have something to do with riders manipulating lower averages from the first six matches of the following season such that a 2.00 rider could then be replaced by a 5.00 as the other six riders had collectively dropped 3 points between them, for example. As at the start of a new season the first set of new averages was based entirely on that seasons scores. Making it easy for a 9 pointer to 'take it easy' over the first six matches and lower their average before miraculously rediscovering their form and finishing the season as a 9 pointer. By introducing rolling averages it was then much more difficult for a rider to reduce their average at the start of the season (or at any time) because they'd need to 'take it easy' over 20 matches which is difficult when points = money. I've really no idea why they'd reduce this to 10 matches? That's worse than pre rolling averages. At least then a riders starting average for the following season was based on their performance across the whole of the last season, in which there used to be plenty of matches. Aside from manipulating lower averages for the start of the following season a team guaranteed a play off spot could actually manipulate their averages to have a stronger reserve for the play offs. Say Belle Vue have a commanding lead in the PL with even six matches to go. Could Charles Wright, for example, have six bad matches and find himself at reserve for the play offs? 1 Quote Link to comment Share on other sites More sharing options...

Most seasons many of the play off positions are pretty much guaranteed for some teams by the end of July so plenty of scope for manipulation I would think...

If so, including them AND all the doubling up Div One HL's currently sat on 6/7/8/9 point averages might be difficult... Therefore the current lads drop a decimal point or two and they can then get team places to keep doubling up next year... As if they dont double up, they then may want more to ride in Div 2...

Did I just really say that...... where you conjuring the extra higher averaged riders from then? So that all teams can have a team average of 45 points? Otherwise you'll have some teams averaging 45 points whilst others average maybe 39 points, if you're building from the existing pool of riders.

Wouldn't Woffinden come back in on his previous top division average which was about 7.50 or something ridiculously low. So even if riders did drop points you'd have the likes of Sam Masters on a higher average than him. If they can attract the GP stars back, even if Poland allow it, just grade them. They're already doing it with rising stars. Of course a riders average would play a part in defining the grade but averages to 2 decimal places just aren't accurate enough to rank individual riders. They're only even an indication 1 Quote Link to comment Share on other sites More sharing options...

They're only even an indication Far too many variables make up averages... Eg a riders liking for a home track v his away performances, his position in the team, how many points get "gifted" or "lost" by engine failures, falls, riders "giving up at the back" and riders "managing" their own averages, riding in meetings missing the best riders through fixture clashes, team riding by riding "shot gun" and probably many more... Grade them all... 1 Quote Link to comment Share on other sites More sharing options...

In answer to your first line, does the BSPL ever explain why they make decisions or ignore rules in their own regulations. Quote Link to comment Share on other sites More sharing options...
