Eyes not spreadsheets
Talking about both if one poor game from someone who's been dominating for ages means they slip off 1st place for someone who hasn't been anywhere near as dominant over even the last 6 months.

Herath has definitely been as dominant in the Aus and Zim series.

Ratings should be for specific fielding positions, maybe. How can a slip fielder be compared to a thirdman?

Why is Dravid the worst fielder of all time?

Oh my. Paul Collingwood #7 worst fielder of all time

A couple of points here - there are quite a few fielders who do much better in ODIs than Tests. Collingwood and Steve Smith (#16 worst) are good examples here. Collingwood is #7 best in ODIs and Steve Smith is #14. Dravid is also better in ODIs.

"Worst" is a strong word but it's more like they have also been involved in a lot of fielding events and been consistently below average according to the data (20%+ drop rates over 50+ matches).

And one major issue. Let us take Kaushal Silva vs ABDV.
Silva has 4 drops in 31 attempts. ABDV has 13 drops in 187 chances. Silva is ranked at 8 and AB at 16. Silva seems to be ranked higher because he has only 3 fewer great catches even though AB has played so many matches.

When you have such gigantic discrepancies in sample sizes, you can be fairly certain that AB's numbers are not a fluke event. We can say something like that about Silva with very low certainty. You need to adjust Silva's rankings downwards for that.

Do you already look for words or phrases that indicate a very good catch or punish a fielder for dropping a dolly?

You're probably right. I just haven't spent time on fielding since I initially looked at it just because I lost a bit of interest since I found fielding impact was not as high as I thought it would be (on average just 5% or so of win shares can be attributed to fielding in T20s for example).

I look for great catch and difficult catch key words - not specific separation of dollies though.

How do you define win share?

Win percentage attribution. Say a team is chasing 275 in an ODI and need 150 in 30 over with 5 wickets in hand the odds are 60%. In the next over the batsman makes 10 runs and the odds improve to 65%. That 5% win percentage change is attributed to the batsman (+0.05) and the bowler gets the opposite (-0.05).

A fielding example is say a fielder gets a great catch at that point instead and no runs are scored in the over with the loss of the wicket. 85% (say) of the credit for the wicket goes to the fielder (since it was a great catch) and 15% goes to the bowler.

Oh cool.. And what is the formula used? Btw is there a document detailing all this?

You can find the evolution of it here:
http://www.cricketweb.net/forum/cricket-chat/65815-win-shares-finding-clutch-performers.html

Overview here:
cricrate | Methodology - ODI Win Shares

In short, odds are calculated using similar historical match situtations (what % of matches ended up being wins = win odds). cricodds is built on this idea:

Increased penalty for early innings due to issue with slightly overrating de Kock - he is still at top but is much closer to the others (Kohli will replace him after the current test most likely).

Test update:

- Kohli jumps to #3: cricrate | Current Ratings - Test Batting
- Rabada moves to #5, Abbott jumps to #10: cricrate | Current Ratings - Test Bowling
- Bairstow moves to the top: cricrate | Current Ratings - Test Fielding

ODI update:

- Warner reaches #2, 2nd highest ever current rating by an Aussie (after Dean Jones): cricrate | Current Ratings - ODI Batting
- Warner's 156 ranked #34 all-time: cricrate | Performance Ratings - ODI Batting
