There was an article in the ACS journal which gave a method of adjusting a player's career statistics, though it focused on English players.
The method is basically:
- let N be the number of seasons in which the player played (here 'summer of 2000' and 'away series in 2000-01' would count as 2 seasons).
- let M be the number of matches that England played in those seasons.
- the adjustment factor for the players figures (matches played, runs scored etc) is then 5N/M.
The assumption here is that an 'average' season would include 5 Tests.
