Some obvious disclaimers:

• Only level 70 characters are included, so this will not necessarily reflect the realm as a whole
• Not all level 70 characters are counted. Realms with low population counts will have skewed and unreliable figures.
• Since there is a tendancy for guildmates to also be included, this effect can skew numbers greatly towards one side.
• Since this calculates by character and not by player, this effect can skew numbers greatly towards one side.
• This is in no way suggesting that the real overall realm counts are anywhere close to the figures presented below.
