You didnt have to do any maths here, was a waste of your time lol
If you go to the Runescape Homepage, it displays how many people are currently playing "Runescape", which includes 07 and EOC combined, as regardless of separate servers, they are both, Runescape.
And to work out how many are playing each, all you had to do was go onto the 07 homepage, and look at the number of players currently playing, then navigate back to the Runescape homepage and subtract the 07 figure from the combined figure on the homepage, and bam, you have your numbers separated.
But i do agree it is misleading, of course many players are going to quit EOC for 07, and they can't let it display "they are currently 30k players online", because it will make the game look like an absolute fail.
I think the intention of this idea was just to boost figures, many players have come back to Runescape specifically for 07, but they've chucked the figures together, so now it looks like an extra 50k players are online, when really we're all playing the side-server so to speak.
