Those stats would be a bit meaningless though without some long-term trending and analysis. You can't, for example, just look at the total of players and call a percentage, as 100% of players who have ever logged in and played open were still in Solo until their first jump. Players can be in any mode they please at any time, so you can't just say Player X is purely Open, as he may well likely switch to Solo when network or instancing goes wonky, just to continue playing. You can't say Player Y is Solo only, because he may switch to Open when he feels like it, just you never find him.
