F-400 Rankings with 1 year instead of 2 years

[Leehar]

i thought the history went back 6 years?

War value decays 25% every 6 months.

There is an easy way to test this, at least at the top of the table.
6 of the top 7 clans under the one year system are playing each other currently.
TOFU, TSM, Empire get their best or the same ranking position on a 2 year ranking.
PACK, AFOS,AOC get their best places under a 1 year ranking
So if TOFU beat PACK
Empire beat AOC
TSM beat AFOS
The 2 year ranking is a more accurate reflection of the relative strength of clans
But if
PACK beat TOFU
AOC beat EMP
AFOS beat TSM
Then the 1 year ranking is better

I disagree that you can extrapolate that to the rest of the clans.

He pretty clearly said that the test was for the top of the table.

And very good point, LC! We will see.

Incidentally, anyone who is willing to do enough data mining can probably determine which formula is more accurate based on the past year's results. If you calculate the 1-year results for the past 12-15 months, you can determine whether or not the 1-year or 2-year formula more accurately predicted the winners of the previous year's challenges.

The thing is, that 1year ranking better reflects current form of clans.

The 2 year is better for overall ranking.
