Agreed. If sorted by matches into the season, instead of calendar date (which can be delayed by travel days off and rain postponements), then you can clearly see that 2012 is the earliest match to get to the 4th win.
True in terms of number of total matches required to reach that 4th win - what also plays a role is the widely varying start dates of the various seasons, which will become progressively less of a factor as we get deeper into the season.
