No reason to compare the home record of one player to an away country of another If trying to get a measure of how tough they had it are. 50% and 5% of games (or whatever the numbers are for particular players) are vastly different.Nine years isn't too short, but it is short relative to ATG discussions which he does have the right to be involved in. The RPW across Ken Barrington's overseas tests is 37.64. That's very high. Of course, his overseas record is still excellent, but he clearly had kind conditions away from home by and large.
An argument in Barrington's favour against Dravid is having tougher home conditions. But this is hindered a lot by Dravid's great record in England.
Doubt there is much in common for English pitches/general playing conditions 50 years apart Either.
