For those that don't know (much) about Kinchranks, please see the original post by Daniel: http://www.kinch2002.com/kinchranks/

However, I feel that Kinchranks are still missing an important element: current form.

With kinchranks, your PB is used for calculations. However, we see people that no longer compete in certain events, or have stopped practicing them, and no longer get results in competition that are close to their PB.

To tackle this issue, I propose a 'running' Kinchranks, which take all your results over the past 12 months into account.

How would this work:

1) Let n be the number of non-DNF averages (or single, depending on event) obtained in the last 12 months

2) Multiply the most recent result by n, the one-to-most recent by n-1, etc etc, the least recent one by 1

3) Add up all results from step 2, and divide by (n*(n-1))/2 (which is the sum of all numbers 1 up to and including n)

4) Use the result from step 3 for the calculation of the running Kinchrank (divide WR/CR/NR over the result from step 3, and multiply by 100)

A lucky PB will still help your kinchranks, but only for 12 months, and the effect will fade quickly as you get more results in (as the multiplier for the lucky PB will drop off).

Any thought/comments/remarks/improvements/questions/etc?
