Well.. I m guessing the story behind those numbers would be more telling than just the numbers itself but I am not in the mood for statistic based debates.. I agree with your analysis to an extent, that he is obviously much more comfortable in these conditions than in those conditions but I do think he has become a worse player abroad than he was as recently as 3 or 4 years ago due to a lot of laziness and indiscipline than anything else.
His innings yesterday for instance, it was clear he still has the same issues in terms of footwork and fitness (compared to his pomp) but at least his mind was in a better state and he seemed to be thinking with more clarity and that helped him get those runs.
Most first class cricketers could of tonned up on that pitch, with their eyes closed yesterday.
When the ball doesn't get above the knee roll, it's pretty easy to smack.
