Quest of better rain rules

[V. JAYADEVAN]

Make up factor concept is a very innovative concept to improve the ODI targets when the interruption is during the batting of team-2 and only very few overs are left to play when the match resumes.

D/L is better than the others.

I have gone through the VJD system and implemented them in some of my matches in the domestic cricket in India. I think it is quite competitive as much as Duckworth Louis is.


But my point is how do you decide a match with mere calculations and based on a lot of matches? No two matches are the same, do you agree, Mr. V. Jayadevan?

Could you please elaborate as to how you take into consideration, the players' calibre?

For instance, I as a captain send all my tail enders to bat first and later on send my BATSMEN to the crease? How does either your system or Duckworth Louis consider this?

The Board of Control for Cricket in India (BCCI) is reported to be considering the VJD system for use in domestic cricket this season as an alternative to the Duckworth-Lewis method, used to calculate targets in rain-interrupted One-Day Internationals. Sunil Gavaskar was impressed with the system and had appreciated the efforts by V Jayadevan, a 45-year-old civil engineer who has an M.Tech degree from the Indian Institute of Technology (IIT) and who works at the Kerala Engineering Research Institute (KERI) in Thrissur. His procedure, called the J-method, based on sound mathematical principles, claims to be devoid of D/L's shortcomings. You can now download all details of the system including the latest version of the software from vjdcricket.googlepages.com

Having read the article by VJD I am of the opinion that his proposal has much to offer and could be less likely to come up with rain-delayed requirements that are not only improbable but unachievable considering the examples that he gives. Has anyone similar stories to tell of the J-method?

One possible flaw in any method is the assumption that an interruption comes as a surprise to the teams. In reality, there's more often than not advance warning of the possibility, and thus the opportunity to "game the system."

Also, it's worth considering that there's a basic philosophical difference with respect to interruptions during the reply. Specifically, D/L allows the win probability of the team with the advantage to grow gradually as the delay lengthens, eventually reaching 100%. VJD, on the other hand, attempts to keep the probability constant all the way until abandonment, at which time it perforce jumps to 100%. (Perhaps, in league situations, the points should be divided in proportion to the probability at abandonment?) I don't think either philosophy is blatantly invalid, but the difference is certainly a point to ponder.

You can usually tell when black clouds are rolling over, but(certainly in the UK) you don't know whether they are going to dump on you or hold off for another half-hour.

It's difficult to game the D/L system - if you try to increase the scoring rate because you think it's going to rain, there's the possibility that you lose a couple of wickets and push up the par score.

If the VJD method brings more transparency then I am all for it. The ICC seem to be keeping the duckworth-lewis calculations a big secret due to "commercial sensitivity" LOL!! This kind of makes the DL method a farce as umpires can basically pick any number they chose.

The book written by Frank Duckworth and Tony Lewis in 2004 has the r2 version table of the standard edition which is now so out of date that it is probably worth ignoring entirely, sorry accumen but the book just isn't worth the fee at the moment, it is rarely ever correct and the G50 par score for T20 wasn't considered.

ICC should release the DL tables so people can trust it or switch to a method that is available to the public.

[Acumen]

Just contacted Frank Duckworth and he assures me that they "reviewed the available data in 2005 and came to the conclusion that no changes in the parameters, and hence the tables, were justified. We are reviewing the latest data again this summer, but we doubt we shall conclude that they should be changed dramatically, if at all. We have seen no published analyses to suggest that the tables are 'out of date'."

I would be interested to receive examples of any errors and I will take them up with them.

Make up factor concept is an innovative technique devised by me 3 years ago to resolve the problem in interrupted cricket matches with very few overs/balls left when the game resumes after interruption. An earlier version of this article was published here two years back.

The modified version "MakeupFactor.PDF" can be found on groups.google.com/group/AcumenNews/files.

With T20 matches becoming very frequent, the relevance of this new concept is very high now.
