Batting Consistency Rating: How consistent is the Batting of Our Players?

[babubangla]

We all are concerned about the batting consistency of our national team players. I was trying to figure out a way assign a numerical measurement of batting consistency.
Here is the consistency rating of our players. Higher rating means high inconsistency and lower rating means better consistency.

Batting Consistency Rating



The rating shows the numbers of innings interval a batsman takes to bat a certain score. The consistency rating table shows the consistency level of our national team batsman. I included rating of Steve Waugh and Sachin Tendulker to give an idea of wolrd-class batting consistency level.

Consistency Rating at 30+
For scoring 30 & up, the 3 most consistent players are:
1. Manjurul Islan Rana (1.20)
2. Rajin Saleh (1.25)
3. Habibul Bashar (1.31)
It shows, on an average, Manjurul Islam Rana scores a 30+ innings after a interval of 1.20 innings. For Sachin Tendulker, the gap of innings is just 0.80.

Consistency Rating at 40+
But the consistency rating changes for higher scores. For scoring a 40+ innings, most consistent players are:
1. Rajin Saleh (1.70)
2. Habibul Bashar (1.79)
3. Nafis Iqbal (2.00)
Interesting thing, Manjurul Islam Rana, the most consistent player at 30+ level, is not good at all at 40+ levels. His rating falls down to 4.50. This means, he is a consistent player in scoring 30’s, but he can’t consistently produce 40+.

Consistency Rating at 50+
For scoring a 50+ innings, most consistent players are:
1. Habibul Bashar (2.05)
2. Nafis Iqbal (3.00)
3. Md. Rafiq (3.25)
To some extent, Habibul Bashar rocks here. Rafiq’s higher rating is kind of inflated by too many not-outs. Next in line for 50+ is Md. Ashraful (4.44). Aftab’s rating is very low all along. It’s because he played too few tests. Also his poor test scoring rates created negative impact on this rating. It will certainly improve as he plays more tests and make big scores.

I hope, this numerical consistency rating will be a handful tool for comparing batting consistency of different players.

Calculation Appendix
Initially I tried with conventional statistical model using standard deviation, kurtosis and skewness. But it was not helpful for various reasons (i.e. too low and too high scores evaluated equally). So, I followed an alternative way to measuring batting consistency level. First I made a chronological list of all the Test Innings played by each batsman. Then I figured out the gap in between the innings to produce different scores. And the final rating is the average of the innings gap for scoring at certain score level. Please see the example below for a simplified version of calculations used in the rating.



The details version of the calculations also makes adjustments for “Not Out” scores and “open-end” intervals. If you are interested, I can provide details of the calculations.

Where did you find these table? Did you come with this yourself?

Tables are generated with Individual Stats complied from Cricinfo. But the Statistical Modeling and calculations are self-producued.

The guys who are doing 40+ in 2 or less are doing okay (Bashar, Nafees, Rajin). The rest need to improve their consistency big time. Ashraful's consistency is pathetic. A 40+ in every 4.44 innings. Javed Omar scores a 40+ every 5 innings! An opener needs to do better than that. Aftab is even worse but he hasn't played enough games for us to judge him based on this stat.

Babubangla, good work. We needed to see something like this!

Great Post... Thanx to Mr. BabuBangla

[reyme]

Now thats a great post babubangla!! The selectors should keep an eye on this table while selecting the team. As we see from Sachin ans Steve Waugh's stat, consistency is the key to become a great player.

I remember Dav was giving individual target to national players when he took over, for example, for Sanwar, he was asked to reach a target of 20 something before going for big shots.

[reyme]

I think one of the biggest argument about Alok and Rana as a batsmen now clear as water from this stat. No matter how much formula we try to come up with, the fact is, stat speaks for itself.

I remember the selectors always talked about consistency or performance as the key to get a place in the team. Well now they have a chart to look at and work on.

My question is how come the computer analysts cant come up with a stat like that? What does he do anyways? All the time I see the players look at the video how they got out in his laptop. Just keep a TV in the dressing room then...

[Zobair]

well done sire! you know what could be even more interesting? Looking for a positive (negative) trend. Perhaps an interval of every four innings. Of course for players like Aftab who have played much this would still be rather meaningless, but still we can see which of our players are on the way up and vice versa.


PS: What do you do for a living?

[sadi]

alok is doing worse than mushfiqur?? thats sad..................lol

[Fazal]

Thanks for serious food for thought.

[Rubu]

babubangla finally knew how to use his 3rd day of conferance!

or is it another story?

anyway, a better use of time, this time, i've to say.

since, Dr. Z went to retirement (looks like) we need anyother this type of table guy.

go on babubangla

Hats off to babubangla

in 2 or less are doing okay (Bashar, Nafees, Rajin). The rest need to improve their consistency big time. Ashraful's consistency is pathetic. A 40+ in every 4.44 innings. Javed Omar scores a 40+ every 5 innings! An opener needs to do better than that. Aftab is even worse but he hasn't played enough games for us to judge him based on this stat.

Not only Aftab, Nafees has also played very limited number of matches to count his consistency rate at the same ranks with Bashar-Rajin.

In a nutshell, your batsman are consistently inconsistent

[Spitfire_x86]

For his awesome works, I demand a custom title for babubangla from the forum adimins/mods.

[Ahmed_B]

This seems to be abou Test batting.

The only player who seems to hav good average allthrough.. is Bashar.

Rajin+Rafiq looks good below 50... but I think Rajin will improve more.

Nafees may come good too.

[rupantor]

Rajin Saleh looks prety good for scoring 30's and 40's.
1.25 rating at 30's and 1.70 rating at 40's is very good consistency.
But he certainly need to improve a lot to produce some big scores.
We don't want a specialist batsman to be vulnerable before scoring some big.
