The "runs cost" will also be influenced by the quality of bowling and the other fieldsmen. A strong side is more likely to minimise the consequences of a keeper's missed chnces. For example, Gilchrist's errors in 2005 mattered far more that his much less frequent mistakes in earlier years, because the Australian bowling, apart from Warne [and McGrath at Lords] was relatively poor in 2005.
