koffieboon said: How about just using method one but also include a maximum of points you can get from 1 prediction (for instance 50 points) to better balance over and underpredicting? Another question, will there also be points awarded for total numbers for the last 10 weeks and highest weekly sales and if so how will you weigh these compared to the weekly sales points? |
But then people wouldn't be penalised for being way off mark.
And yes... I didn't do it for last years results, but I was always planning to include the total sales into it... probably add a score for it to peoples totals... but multiply it by 3 or 5. So for instance if after the 10 weeks you get 700 points (which would be a phenomenally low score come to think of it, as the DS and PSP are added) then I would work out the discrepancy for your total sales prediction.... and multiply it by say 5.... most people should get the total within 5-10% I think, which would probably equate to about 25-50 points per console.
I don't think I will do anything with the highest weekly sales though... perhaps just a seperate "award" for it.
