Post 1992, the stats look like this
SL
overall: spin 31.40, pace 34.30
visiting: spin 44.12, pace 36.35
IND
overall: spin 32.78 pace: 35.91
visiting spin 38.66 pace 36.34
Aus
overall: spin 36.34 pace 33.14
visiting: spin 48.63 pace 41.10
This clearly shows spinners average in SL is low due to excellent work of Murali, and visiting spinners ahve found it tougher than pacers to bowl in SL. Similarly in India Kumble, Harbhajan, Raju and Chauhan caused that spinners avrage to drop. Once more, visiting spinners have found it tougher. And Australia, the story is the same. Actually visitng pacers have found SL and India better suited for fast bowling than Australia!!! Once again, the person who faces matters, more than the conditions
You're wasting your time. First of all, the discussion had nothing to do with Murali specifically but about bowlers who will gain advantage in certain conditions whilst other bowlers won't. That is NOT accounted for IN that analysis. Again, Spin is STILL stronger than pace in Sri Lanka and India, showing that they are more ideal for spin. Murali has taken advantage of that and had made the gap between pace and spin even larger (he averages 19 at home and 26 away FFS). Even if the averages were level it'd be damning because on average pacers average lower than spinners so for spinners to be level in one country it clearly shows that it helped them. Very few spinners will average as low as pacers.
Secondly, my point was not regarding merely visitors but the bowlers who bowled at home...because they play half their Tests on pitches suited for THEM.
Thirdly, with regards to Warne and Murali, the point was Australia was much tougher to bowl spin in than Sri Lanka. You haven't/can't disprove that. hence that is an advantage the other doesn't get and it isn't rectified in that analysis.
I think you grossly misunderstood what I am saying. For great spinners like Murali and Warne, the conditions does not matter much. More than conditions, what matters is the batsman who's facing them.
Whilst they can spin the ball anywhere, there are still large varying degrees of benefit on certain pitches. Warne and Murali's performances in Sri Lanka and Australia is a great indicator.
Now going with this argument, Warne would have used "tough" Aussie conditions to better use than others, hence and advantage over others while bowling in Australia?
Whilst that may be true, you missed the point. Warne's tough home conditions are much tougher than Murali's home conditions. Warne plays only a small fraction of his career in Sri Lanka whilst the same goes for Murali in Australia. However, Warne plays half his career at home, whilst Murali does the same. See the difference? The analysis doesn't do anything to address these kinds of discrepancies. Whether it be Warne and Murali or Marshall and Imran.
For me, an analysis that is looking at SR but doesn't factor in the pitch is useless. I don't want another Warne v Murali argument. I just brought it up because it is an obvious example. Get over it. Finito.
