Duckworth Lewis
jim brant
yesterdays C&G semi left me perplexed. Surrey got 173 or so in 48 overs, and
so could not have been expected to get more than (say) 193 had they batted
for the full 50 overs. The game was then reduced to 42 overs, but the target
for Yorkshire was essentially the same as Surrey's score off 48. If they got
173 in 48 overs, what logic indicates that they would have got the same
score had they known they were only going to bat for 42??
Fortunately the issue bacame academic, thanks to GOC (and whoever it was who
dropped him off the first ball), but I would like to understand. Is there a
simple explanation, does anybody know?

No simple answer to Duckworth Lewis - theres a good explanation at:

The crucial bit(s) that cover your anomaly I've pasted underneath.
You'll have to wade through the bit describing resources to make sense
of it all.
I preferred it when 'man with bat hits ball very far.'

"If the side batting first had more resources (R1) available than the
side batting second (R2), the the target to tie the match is calculated
as the first innings score multiplied by (R1/R2) rounded down.
If the side batting first had less resources (R1) available than the
side batting second (R2) then the target is the first innings score plus
the difference between the resources divided by 100 and multiplied by
the typical score in a 50 over match (normally 225, but could be
different - it was 190 in the 1997 ICC Trophy). So if the first side
scored 150, and had resources available of 60%, and the second team had
resources available of 70% when the innings finished, then the target to
tie would be 150 plus (10/100)*225 = 172.5, rounded down to 172.
So the apparently unfair position can arise where if the first innings
is truncated by rain after 40 overs with six wickets lost, then
resources lost would be 24.6, resources available would be 75.4. The
second side might start with 40 overs to play, no wickets lost, and so
have 90.3% resources remaining, more than 74.5% so their target to tie
would be 225*15.8/100 rounded down = 35 more than the first innings
total, even though both sides would have to face 40 overs. The
discrepancy would be because the first side would have been pacing
themselves for 50 overs, and the second would know at the beginning of
their innings that they would only have to face 40 overs"

Article indicates that 'joker' over will be chosen during innings but
no other info offered on this particular proposal. There are other
proposed changes from the existing 1-day format in order to 'appeal to
a new audience' (ECB quote), each innings is alloted 75 minutes and
incoming batsmen are allowed only 90 seconds to take guard, he will be
expected to jog to the middle from a "hot seat" placed next to the
boundary. Umpires will have licence to punish time-wasting by the
batting side with a 5-run penalty. 2 trial games will be played
between a Gloucs Invitation XI and Lashings, the Maidstone based club,
at the County Ground Bristol on Sunday (I assume that means tomorrow).
Play will run from noon until 1815 with a 45-minute gap between games.
Gloucs hope to include Courtney Walsh plus Mohammad Kaif and Dinesh
Mongia from Indian touring squad. The Lashings side can call upon Viv
Richards, Brian Lara and Shoab Akhtar...
