Re: paper: FIRST Championship History Results
Thanks Jim for putting this together. Couldn't you have picked a factor that put 33 in the Top 10?
The waiting factor Jim used is pretty neat. If you ask yourself "how much influence should history have"?
For the "team of the decade", it should probably not have a weighting factor, but if you are curious as to the trend, the effect of weighting is very interesting. The 0.66 weighting allows for:
Current: 1
Last year: 0.66
2 years ago: 0.66*0.66=44%
3 years ago: 0.66^3=29%
4 Years ago: 0.66^4=20%
Jim picked this factor as it best followed the "Student cycle" of 4 years. Not only do you loose those students, but you may also loose some really great parent involvement.
This factor also helps up and coming teams like 1625 and 2056 get the respect due to them. For instance 1625 is just 1 ranking position below 33 even though total points over 10 years, they are less than 50%.
The weighting factor is kind of fun to look at. You can play around with different weightings and see the effect. If you go much lower than 50%, then history really has very little to do with the ranking. For example if you had the same result 2 years in a row then scoring would be 1+0.5 which means that last year has less than 33% influence on your current standing.
P.S. Very cute with the color scheme. There is a way to do Tie-die markers if you are interested.
