This post is written primarily for those cricket fans coming to Offsetting as a result of the WASP being used on BSkyB in Britain to cover the current series between England and Sri Lanka. As with the coverage in New Zealand, it has generated some reaction on Twitter. The aim of this post is to enhance the discussion by addressing some common misconceptions.
Because WASP doesn't take into account the particular players, it provides a measure of how well particular players are doing. For example, imagine that WASP was sitting at 225 in the first innings when a partnership between, say, Sangakkara and Matthews begins, and has risen to 300 by the time the partnership ends. That doesn't mean that WASP was wrong; rather it is a measure of how well those two batsmen have played (or alternatively, how poorly the opposition team have bowled and fielded).
Yes it could. Sometimes, WASP will give a very different answer, partly because of its using a different criterion for fairness and partly details in the implementation, including it having an adjustment for the ease-of-batting conditions. Most of the time, however, it will produce a similar outcome. For example, in the first ODI between Sri Lanka and England, D/L initially set Sri Lanka a target of 259 as a result of the earlier rain interruption; WASP would have set 262. After the second rain interruption, D/L revised the target to 226; WASP would have set 220.
What if I have more questions?
