Guys, I've looked up the 'news' again where the 84% figure came from, but see for yourself:

I don't know if one needs to have studied statistics to guess what went wrong here, but I will try to explain nevertheless.
First of all, take a look at the diagram inside the spoiler. It looks like each active player contributes to total launches. Now, what about grouped up players? Does a group launch mean that every group member is accounted for individually or only the group itself? How are disconnects treated in this regard? None of that is evident, but the differences can have a significant impact on the numbers we see here. To give an example: imagine a group of 4 players launches, but only one launch is registered in total. Whereas if each member would drop solo, a total of 4 launches would be registered. Do you see how such an easy mistake could lower the total group launches?
Secondly, each player can contribute to each category listed there (solo, 2-, 3-, 4-man groups). That is neither mentioned nor taken into account. Why is that important you ask? Some players play more often than others, so they contribute more to the number of launches in a or more categories. Also, not everybody pugs or groups up exclusively. Furthermore, not every group can build up or maintain the maximum number of players over the course of a session. By looking at total launches alone, you would never know if a minority or a majority of players has an impact on a diagram category.
All of the above hints at significant overlap in the data presented to us. To draw any meaningful conclusions, it really needs to be cleaned up. PGI first needs to make sure they have accounted for all players in groups correctly. That means every player counts as a launch, not just the group itself. Secondly, they need to link each launch to a player ID so they can feed a normal distribution and see how people fit into the bigger picture, how regularly they form groups, how big they are etc. Launches alone don't tell the whole story.
So, what do you think? Should PGI take another look at their data?
