Format
The format was changed from previous tournaments in that a complete round-robin replaced the use of two qualifying groups. The initial draw was released with eight competing countries and 28 round-robin matches. In late 1991, South Africa were re-admitted to the International Cricket Council and the draw was amended to include them. The revised draw included 36 round-robin matches plus the two semi-finals and the final.
The rule for calculating the target score for the team batting second in rain-affected matches was also changed. The previous rule simply multiplied the run rate of the team batting first by the number of overs available to the team batting second. This rule was deemed to be too much in favour of the team batting second. In an attempt to rectify this, the target score would now be calcuated by the "highest scoring overs" formula.
In this system, if the team batting second had 44 overs available, their target score would be one greater than the 44 highest scoring overs of the team batting first. While the reasoning behind the system was sound, the timing of rain interruptions remained problematic: as the semi-final between England and South Africa demonstrated, where a difficult but eminently reachable 22 runs off 13 balls was reduced to 22 off 7 (the least productive over, a maiden, being deducted) and finally 21 off 1 ball (the next least productive over having given 1 run). It was seen that, if the interruption came during the second innings, the side batting second was at a significant disadvantage - one which was only overcome once, in fact, in England's group-stage victory over South Africa.
