# Innings Power Factor: a new measure for ODI innings

Alex Tierno had suggested that I create a new factor for ODI innings, incorporating three features of an ODI innings: runs, scoring rate and contribution to team score

This piece was written in collaboration with Alex Tierno

I have attempted something new for "It Figures" in this article. Almost on a continuous basis, many of the readers have offered suggestions for analysis. Some of these have been answered as a response to the comment. Some require creation and publishing of tables in existing articles. Once in a while I get a suggestion which warrants a separate article. This is the first one created based on this premise. In future when such an idea comes up, I will do a similar publishing.

This is based on a suggestion made by Alex Tierno a few months back. I was tied up with various things and only now could I do justice to the suggestion. Alex, in consultation with me, has also has polished the idea with some tweaking recently.

Alex has suggested that I create a new factor for ODI innings which he called "Destructive index". I have called that the "Innings Power Factor". This is a single factor which incorporates the three major features of an ODI innings: runs, scoring rate and contribution to team score.

I will respond to reader comments in a general manner prior to publishing. However Alex can respond to these in a summary fashion after publishing.

The formula used is

Innings Power Factor (IPF) = Runs scored * Scoring rate * % of Team score.

The more I studied this the more I was impressed with the simplicity and effectiveness of this as a measure of ODI innings. The higher each of these factor is, the more the value of the innings. At the same time, the introduction of the % of Team score moderates the factor as exampled below.

Let us take two examples. a 50 in 20 balls would get 125 points using the first two factors. A 125 in 125 balls would also result in a value of 125 points. However the % of Team score for the first innings is likely to be 15-25% and 40-50% for the second. This takes care of higher valuation of higher scores.

It should be noted that this factor, being a pure batting one, does not take into account team strengths, bowling quality, pitch type, innings status, result et al. If all these factors are introduced it will become another Ratings exercise. So please do not send any comments on the exclusion of these factors. In a way this is similar to the 100s-50s. A 100 is a hundred irrespective of when, where and who it was scored against. I also like this measure since it does not have the 99 to 100 problem I have earlier talked about.

This is an unforgiving measure and requires all three factors to work together to finish with a reasonable value. Cameos tend to lose out. At the end of the article I have done a table which takes into account only the first two values.

I briefly toyed with the idea of having a fourth factor, the Result (1.1/1.0 or 1.0/0.9). I gave up for two reasons. It penalizes Coventry/Tendulkar/Hayden/RASmith/Ponting et al unfairly. They could not have done anything more. Also in the top-100, 85 are wins, so this factor will not have any great impact.

The analysis is done in two parts. In the first part, all the innings are analysed and the IPF calculated, sequenced and the table drawn up. By a perusal of this table I have determined that an IPF of 70 (100 off 60 out of 240) translates into an outstanding performance and one above 40 (80 off 50 out of 250) is a very good performance. Also IPF values above 10 (50 off 50 out of 250) translate into good performances. At the other end, only IPF values of below 2.0 might be termed unsuccessful innings. These summaries are posted into the player data and Player tables are drawn up.

Readers, myself included, would be surprised at the top entry. However a careful perusal of McCullum's blitzkrieg, about which I had come out with an article recently, justifies the position. A middling score, boosted by an unbelievable scoring rate and an amazingly high % of Team score has propelled this innings to the top. Those who question why McCullum's innings outshines Richards'/Jayasuriya's/Anwar's/Kapil's masterpieces should note that McCullum's innings meets Alex's "destructiveness" characteristic to a T.

Then come the 6 famous innings by Anwar/Coventry/Richards/Jayasuriya/Dhoni/Kapil. The odd innings which splits these six is Izaz Ahmed's Lahore demolition of India.

In the top 37 100+ innings, Richards and Jayasuriya have four innings each, Tendulkar has three and Gilchrist and Lara have two each.

Out of the 446 70+ innings, 238 (53.4%) are in the first innings.

Now let us see the player tables.

Two 80s greats, Zaheer Abbas and Richards lead this table with averages exceeding 13.00. Richards has achieved this in over 150 innings. However note the high average of Tendulkar, 12.53 achieved in 425 innings. Then come a string of modern ODI stalwarts.

```
Tendulkar has 138 innings which meet the 10 points cut-off, 7 of these are the higher level performances exceeding 70 points. Jayasuriya follows with 99 performances, 8 at the top level and then follows Ponting with 90. Inzamam-ul-haq, Ganguly and Lara follow next. The presence of that Sri Lankan great, de Silva, in no.10 position is heart-warming. Two days during early-1996 are justification for this place.

```
Since the number of matches varies considerably, I have also introduced a % value, which is the IPFs / ODI Inns. Richards leads in this measure with 34.7%, followed by Pietersen with 34.1%, Smith with 34.0%, Zaheer Abbas with 32.5% and Tendulkar with a high 32.5% despite playing 425 innings. This means that these great players produced a very good batting performance once in three innings. That is really something. Now the chronicle of failures. Mike Hussey has failed to deliver in only 38.2% of the innings, Zaheer Abbas 38.3% and Michael Bevan, 39.8%. It can be seen that most of these batsmen play in the middle order.

Now comes a composite value which is the % failure - % success. The lower this value is the more effective the batsman is. The above table has been ordered in the increasing order of this difference %.

Zaheer Abbas is the top batsman with a differential % value of just 5%. The great Richards follows next with 6.59% and then two modern greats, Pietersen and Hussey, with differential % below 10. Two olden day greats, Greenidge and Jones, split the four modern giants, Smith, Tendulkar, Hayden and Ponting.

The more I see the table the more I feel that this is the single table which encompasses the ODI greats in full.

Alex also wanted me to do a calculation excluding the third moderating factor, the % of Team score. In other words make this a pure batting individual factor. The above table is an intriguing one. Again, it is a surprise to see Boucher on top. However his is a big century at a scoring rate above 2.00. Similarly Jayasuriya's innings finds its place. It is amazing that a score as low as Afridi's 102 has found its place in the top-10.

Out of the 379 125+ innings, 264 (70%) are in the first innings. This is a marked change to the reasonably equal split for IPF. Possibly the uncertainty of the target for the first innings might have contributed to this disparity.

In the revised table there is only one change. Kapil Dev has secured 221.92 points for his 175* and moves to 21st place. The complete table has not been replaced.
