I think it was cricinfo that interviewed Duckworth/Lewis after the Windies game. Typical stats guy response- the numbers don't lie and the windies were 11 ahead of D/L at 14 balls. Worked with a few stats guys in my job and when it comes to numbers they do tend to have common sense bypass. How does a team that averaged, yes averaged 9.55 over 20 overs have to defend 10 an over for a team who has just 6 overs to bat. England scored 60 in 6 at the start - yes fielding restrictions were in place but the Windies had 10 wickets and only 22 balls to get 30. A better guide would be englands last 5 overs where 76 were scored.
I heard Ireland would of had 61 off 9 overs, again barely half a run an over more with 10 wickets in hand than Englands average run rate. England scored 65-70 odd in the last 9 or 10 overs - again a better guide than D/L, but low given the wickets in hand.
D/L strike me as clever chaps but it strikes me as odd they haven't looked it this for shortened games.
