The first is that the recent innings of a batsman give a good indication of what his next innings will be. This isn't all that true - I have some graphs on the topic <A HREF="http://pappubahry.blogspot.com/2007/10/concept-of-form-in-cricket-has.html" REL="nofollow">here</A>, which show that while it might be a good indication for some players, it isn't for others. And generally, any effect of "form" is quite weak.<BR/><BR/>The second problem is that it doesn't take into account the current score of the batsman. Once again I have graphs. :) They are <A HREF="http://pappubahry.blogspot.com/2007/11/not-outs-and-batting-averages.html" REL="nofollow">here</A>. Narayan's extended batting average can change with a score of nought not out! It's not realistic at all.David Barryhttps://www.blogger.com/profile/08378763233797445502noreply@blogger.comtag:blogger.com,1999:blog-22713811.post-32908172282402421422007-12-26T13:14:00.000+01:002007-12-26T13:14:00.000+01:00Interesting David.Have you read the blog on cricin...Interesting David.<BR/><BR/>Have you read the blog on cricinfo regarding the extended batting average? It is a modified average and takes into account 'not out' innings with a different perspective.
