Consider the recent neutral test series in England. Pakistan's bowlers used the conditions just as well as England bowlers would have, and it is likely that Australia would have batted just as badly against England, primarily because the Aus batsmen weren't used the pitches/conditions. If the unfamiliarity of pitches is half the equation, the other half would be a host of fluctuating variables.
Well, that's true. But then you have to get into a series by series analysis of who took advantage of what conditions. That seems tedious. It's far more easier just assuming the home team is the more suited to their conditions than the opposition - that's probably more or less true anyway; whilst in neutral matches you'd have to make an argument for each venue favouring which team.
The difference is that Tendulkar is more likely to destroy the opposition bowlers than Ponting. Not by much of course, just enough.
But their averages mean the likelihood of Tendulkar destroying an attack is practically the same as Ponting's. The extent of which, although favours Tendulkar; is still minute.
With their aforementioned SRs:
If Tendulkar scores 100 runs, he'll do so off 116 balls.
If Ponting scores 100 runs, he'll do so off 123 balls.
The likelihood of runs scored is determined by average - and we know that it's practically neck and neck there. SR is how many runs they'll score for every 100 balls they face. It's not going to determine the likelihood of destruction, just the extent.
It's like saying when Afridi gets going ; he is more likely to destroy them more than Tendulkar will (facing many balls/SR). However, the likelihood of him getting going is much less than Tendulkar's (difference between their averages).
I think your point is more valid with reference to 100s/per inning or something which Tendulkar is ahead by a way.
