Miriam, well done for spotting my typos - I wrote the notes whilst looking at the spreadsheet - and missed out the line for 4 points and subsequently the rest were wrong. I've edited the original with the correct figures.
(And of course the women's has/had the same error)

And don't forget, the calculations for percentage difference are factored below WR100. The formula is 100(Predicted - Actual)/Actual and then multiplied by Actual/100

So for any actuals below WR 100, cancelling out the 100/Actual x Actual/100, you end up with (Predicted - Actual)?

So basically their number of places out will be their adjusted % out for scoring purposes - eg. 10 places out would score 4, 18 places out would score 2?

Certainly raises the stakes for trying to make accurate WR predictions for our very top players whereas it was previously difficult to get WR points for such as Jack and Emma unless you were very close.
