June 2009 differences solved.
Ghana - Uganda (May 31st) wasn't included in the June 2009 FIFA Ranking calculation, while Qatar - Iraq 1 - 0 (May 31st) was removed from the results (I don't know why).
Comparing the official June 2009 ranking with the last FIFA Ranking update I posted on June 1st, I have a 30 points difference for England and there are another 3 countries with smaller, yet completely unexpected differences: Trinidad and Tobago (4 points), Greece (2 points) and Japan (1 point).
There's also Armenia with 23 points, but I never had official data for them.
Working with FIFA's Information Services department at the moment to get to the bottom of this.
