Ideal population distribution

[Lojik]

What do you guys think the ideal distribution of levels during classic (before kunark launch) of levels would be? I thought about this when doing a /who count earlier this week, and roughly 1 in 4 people online were level 60 and 3/8 were level 55+. Should the majority of the population be around 25? 30? Somewhat normally distributed? How long would you imagine it wouuld take for green to with an average population of 3000 (I know this is a big assumption) to surpass this?
