I decided to make this latest OU list with an accompanying tutorial, showing all the inner workings of how the list is actually compiled.
First of all, all the statistics from July, August and September (the previous three months) are collected, and each usage is divided by the total number of usages for each month. Then, each Pokemon is provided a score, using the following formula:
This provides an approximate predicted usage for the Pokemon for the following months, based on a formula that was found by observing past usage statistics.
Afterwards, the sum of all scores is found, obtaining a number that is extremely close to 1. Finally, this sum is divided by 176.1407, and this becomes the cut-off point for OU. The Pokemon obtaining a score higher than this cut-off point become OU, and the others do not make the coveted list.
Here is a chart showing all the usages and scores of the 60 Pokemon that scored the highest scores for this OU list:
This means that the top 47 Pokemon in the list are OU, namely:
This means that we welcome a new Pokemon in OU, Roserade!
And sadly, we say goodbye to three Pokemon: Alakazam, Rhyperior and Umbreon.
Hopefully this answers some questions about how the OU list is compiled. :)

Code:
Score = (Usage_Sep * 20 + Usage_Aug * 3 + Usage_Jul) / 24
Afterwards, the sum of all scores is found, obtaining a number that is extremely close to 1. Finally, this sum is divided by 176.1407, and this becomes the cut-off point for OU. The Pokemon obtaining a score higher than this cut-off point become OU, and the others do not make the coveted list.
