Perhaps the 1992 system would have been fairer to chop off the median overs.
The majority of mathematical models for pricing etc. are aimed at determining the 'indifference' value at the present time. This seams to be the crux of the D/L system. Both teams should be indifferent to the revised target as they have been given a 'best fit' present value that is equivalent to the initial situation.
Given the recent D/L situations in the Australia/New Zealand series, I think it would be interesting to have a bit of discussion regarding this 'score prediction' series.
In the 2nd ODI of the series, the NZ's total was reduced by 5 overs and 8 runs. In the 4th ODI, Australia's chase was reduced by 16 overs and 34 runs.
I have no idea how the system works. I have looked it up on Wikipedia and tried to make sense of it, but it is certainly not simple. Looking at the above reductions, they appear pretty unfair to the chasing side. What do you guys reckon?
I can see that it is somewhat reasonable in that chasing a score at a high run rate is easier over 20 overs than a score at a moderate run rate over 50 (if that makes sense), however I can't see how 5 overs for 8 runs really makes sense.
I would be interested to hear what the CW community thinks of the D/L system, if it is a bad system, what would be better?
Thanks for digging that up, Sir Alex. I'll merge it in a second.
WRT AlanJLegend, I think it reflects the fact that teams are getting better at chasing, and that with a known target one can better structure their innings. They can also afford to take more risks, as the loss of wickets may not be as important with less overs available to score.
Yes I think it is the fairest system available in the given cirucmstances. The fact that it is a bit boring to comprehend doesn't mean it is a wack job. It gives value to wickets held in hand at the time of cut off which I believe is a fantastic concept as compared to the silly maiden overs chop that existed during the 1992 World Cup.
It's hard to get your head around at first but once you fully understand how it works and why, you'll realise it's by far the best method and is generally very fair to both sides.

If we look at ODI v T20, a "good" first innings score (i.e. one you expect to win more often than not is, I'd imagine, 250). In a T20, you're probably feeling about the same for 160. That's a decrease of 30 overs (60%) vs a decrease of 90 runs (36% less). Someone else who doesn't need to go referee in three minutes can dig through Statsguru and find the exact 50-50 win-loss first innings scores, I'm sure, but I'd imagine they'll be in that range.

Varies heavily based on conditions though, obvz.
Just to put that into perspective, when New Zealand hit 245 in the third ODI, did anyone think they'd got a good total?
Probably duffed up this statsguru search but....
Records since ODIs began : Team records | One-Day Internationals | Cricinfo Statsguru | Cricinfo.com
5.15*50 = 257.5
Last decade : Team records | One-Day Internationals | Cricinfo Statsguru | Cricinfo.com
5.51*50 = 275.5
In the last two years : Team records | One-Day Internationals | Cricinfo Statsguru | Cricinfo.com
5.90*50 = 295
The system of the DL could actually be scraped to point if the ODI structure was slightly adjusted if the game was broken down into quarters. (25-25-25-25)
if it rained in the 1st quarter lets say for 4 overs.
the 1st quarter and the second quarter are both reduced by two overs 23-23-25-25
if it rains in the second you adjust the second and the third
if it rains in the third you adjust the third and the forth.
if it rains in the forth this is the only time you use the DL system because the team the batter first has already batted out their 50 complete overs.
NB only 10 wickets as per normal ODI.
Nah, might as well play Baseball.
