@RicFinlay World Series Cricket possibly have an impact on the the 70's drop?

Here is another take: strike-rates in the Sheffield Shield were heading up BEFORE the advent of the BBL:
English
@AdityaS41869751 Just as accurate as those after 1900. We know the number of balls bowled and the runs scored - that's all we need to calculate it.
English
@RicFinlay Great work. Obviously lots of factors involved but it prompts me to ask how accurate are strike rate calculations from before 1900?
English
@RicFinlay Interesting that Bradman's effect on the batting average seems more evident in the 1920s than the 1930s. Perhaps due to Ponsford and Kippax too?
English
So this seems to suggest there is a case for stating that the BBL has had an influence on the long-form of the game. But not discounting the possible change in the preparation of pitches to favour bowlers more, which is harder to measure.
English
Now it gets interesting: correlation between average and strike rate from 1996-2010 (pre-BBL) is 0.52 - moderate positive correlation (ie, as average goes up, so does strike rate). But since 2011 (BBL era), it drops to 0.15 - virtually no correlation! And 1892-2010, it is 0.37.
Ric Finlay@RicFinlay
Interesting to note that the Correlation Coefficient for Average and Strike Rate is only 0.32 - weak positive. Batters threatened with imminent dismissal in unfavourable conditions tend to hit out while they can?
English
@jimmaxcricket No, strike rates virtually unchanged - see my subsequent graph - T20 influence...
English
Assume bowlers strike rates are heading down too Ric? Should we lobby the Reserve bank boss ??

@filbuddi @PeteWargent That’s right - it’s over a number of seasons…
English
@RicFinlay @PeteWargent How come career averages of most top order bats in shield are in 30s ? Can’t be one season

@RicFinlay Thanks Ric ~ this is really interesting reading, even for a Pom living near Edgbaston.
If you want a project as you enter autumn, do feel free to produce similar for the County Championship 😉 ….

And here, for context, are the season batting averages and strike rate for the whole Sheffield Shield comp from 1892...

@BrisVegasMale Undoubtedly a factor - taking the best players away...
English
@RicFinlay Do you think it has anything to do with Test cricketers used to play a more significant portion of the Shield season ?
English
@RicFinlay When did we last see a batsmen score 1000 runs in a season, Bevo ?
English
@PeteWargent First year of Sheffield Shield, 1892-93, strike rate was 37.8, the lowest ever!
English
@RicFinlay assume run rates are lower? there have been some serious struggle sessions
English
@toddgoulder I haven't measured it, but I think that would be right.
English
@RicFinlay Overs bowled by frontline spinners also trending down?
English
@PeteWargent No, actually. In the last match here, the batters in Tassie's first innings clattered along at 4.5 an over for the most part, hitting out before the inevitable dismissal came. Teams going at 50 sr for the last 30 years consistently, whereas before, that was rare.
