    I mean it's kind of both since there is an additional longevity bonus that complicates matters, but when thinking about the confidence interval you can think of it as both:
    - most likely performance by player
    - accuracy of career ratings measure
    cricrate - follow twitter and facebook for updates

    Changed the Test Team ratings to be 50% less fickle (literally):

    Also viriya a minor thing, but is there any chance you can allow an option to view more per page. If readers could select 50, 100 or all on the page would be just a little easier to navigate instead of clicking next per 15.

    The rankings are starting to take shape, good to see.
    This is done.

    After some painful data work this is finally done. Added a new minor factor "Series status" for Tests (will add for ODIs soon) where performances in dead rubbers have a negative adjustment and deciding games have a positive adjustment. I scraped all historical Test series and checked the series status at each Test.

    Some other minor changes: increased the importance of the home/away factor in Tests and reduced the bonus given to longevity in the career ratings.

    All these changes shuffled things around a lot. Some of the biggest changes:

    Batting performances:
    cricrate | Performance Ratings - Test Batting

    - Brian Lara's 375 drops 35 places to #41
    - Dean Jones's 184* drops 38 places to #49
    - Kumar Sangakkara's 156* jumps 15 places to #2
    - Mark Burgess's 119* jumps 39 places to #26
    - Brian Lara's 226* drops 13 places to #16
    - Mark Butcher's 173* drops 10 places to #12
    - Faoud Bacchus's 250* jumps 41 places to #34
    - Lance Klusener's 118* jumps 34 places to #25
    - Younis Khan's 175* drops 19 places to #27
    - Hashim Amla's 139* jumps 46 places to #47
    - Brian Lara's 221* drops 21 places to #31
    - Gundappa Viswanath's 114* jumps 41 places to #46
    - Rahul Dravid's 270* jumps 12 places to #4
    - Clem Hill's 188* jumps 6 places to #1

    Bowling performances:
    cricrate | Performance Ratings - Test Bowling

    - Max Walker's 6/15 drops 41 places to #75
    - Michael Clarke's 6/9 drops 37 places to #77
    - Hugh Trumble's 7/28 drops 26 places to #50
    - Morne Morkel's 6/23 jumps 34 places to #45

    Batting career:
    cricrate | Career Ratings - Test Batting

    - Jack Hobbs drops 12 places to #26
    - Ross Taylor jumps 22 places to #39
    - Azhar Ali jumps 22 places to #41
    - Herbie Taylor drops 24 places to #72

    Bowling career:
    cricrate | Career Ratings - Test Bowling

    - Ravichandran Ashwin drops 5 places to #12
    - Dale Steyn jumps 2 places to #3
    - Anil Kumble jumps 5 places to #8
    - Curtly Ambrose jumps 4 places to #7
    - Saeed Ajmal jumps 23 places to #41
    - Bill O'Reilly drops 4 places to #13
    - Clarrie Grimmett drops 7 places to #23

    Would love any feedback!

    Thanks for the suggestion!

    Just based on eye check: Butcher's 173* drops, Younis's 175* drops (what inspired me to work on this), Clarke's 6/9 drops - all good signs. Had to do a lot of work to try to make sure the adjustment wasn't too significant but also non-trivial.

    Not a related question and I probably could find out on the website itself, but how does a inning's rating scale with size? Is it linear, or is there a decay?

    The "Runs scored" factor increases linearly till 200, then decays quickly.

    From methodology page (cricrate | Methodology - Test Batting):
    "Runs scored: This is the most significant factor. It values runs linearly upto 200, then each additional run becomes less valuable than the last. This is because scores in excess of 200 are pursued mainly as personal milestones and does not always line up with the team objective."

    That makes sense, but I would have the linear decay starting much earlier than 200 personally (albeit slower). Cribb and I have talked about this a fair bit.

    I went with 200 after looking at the correlation between runs and win % as I recall. The (win + draw) % tended to increase with runs up to around 200. So it's based on actual historical numbers.

    Yeah, fair enough.

    Smitteh is already #4 of all time for Australian batsmen, which is kind of scary tbh.

    Yea forgot to mention that.. although I'm sure him being above Greg Chappell and Steve Waugh career-wise isn't going to be universally agreed upon.

    The numbers are insane though. It's a bit like Ashwin.. seems premature but the numbers are just too good to ignore.
