Bat or Ball?

My Level 1 Series Scores are calculated 'out of context'. Level 2 scores attempt to adjust the values of wickets taken and runs scored according to the average standard of the series. Level 1 scores have an element of adjustment, but only to runs scored. Thus, the ratio of total points allocated to runs scored will offer some indication of whether a series was dominated by the batsmen or the bowlers. A high ratio of runs scored means the batting was dominant, a lower one the bowling.

Here are the ratios for the 'Christmas Tests', which I have been analysing over the last week or so:

Ban v SrL   1.22
NZl v WIn   1.18
Aus v RSA   1.16

I'm surprised that the New Zealand series with West Indies was more 'bat' than the Australia vs South Africa showdown.
