You might have noticed Uganda's and Zambia's points in the official November 2012 FIFA ranking were different from the ones in my November 2012 final preview.
As Ed already noticed, FIFA changed the PSO algorithm after I've sent them an e-mail. Uganda got the full 3 points, while Zambia got 0, instead of the previous method of calculation: 1 for Uganda, 2 for Zambia.
However, there is still another PSO match that wasn't fixed. On 12 July 2011, St. Lucia won against Aruba 4 - 2 (5:4 PSO) after losing the first leg 4 - 2 in Aruba (during the 2014 FIFA World Cup preliminary round).
St. Lucia should have 7 points more (182 instead of 175), while Aruba should have 11 points less (143 instead of 154).
For a couple of hours there were also differences for Thailand and Laos, but FIFA fixed them after another e-mail. They had mistakenly included the Thailand - Laos friendly in the calculation, although that match was no longer an "A" match.
