Rachael, this is excellent stuff, but as DaveGillespie suggests, there must be some extra thing (for want of a better word and I refuse to write "je ne sais pas" on a Cricket board) given to each mark regarding the quality of the bowling immediately before.

Bowlers work out batsmen. Sometimes the calculation takes more than an over. But for the purposes of your system which is certainly workable (I look forward to trying at home) there must be a sort of annotation regarding say three previous balls.
So Hussain who has fallen for the 3c perhaps should have "< v > 3c" for his dismissal.
Being "movement away" "attempted yorker" "movement in" and then out by the 3c method.

This is fun. Hours of pleasure here.

Have you ever looked at one of Bill Frindall's scoring charts?

They might offer you some further ideas.
