how long it takes to hit 60

[Topgunben]

I was reading a thread out of curiosity

http://www.reddit.com/r/project1999/..._to_max_level/

2 of the people commenting said that getting to level 25 is about 1% of the time it take to get to 60. FYI I have/had never gotten to 60. I have a level 30 necro atm, and though I havent kept track of the time it took me to get to 30, I would probably say it was ~ 120 hours of playtime. Maybe 75 hours it took me to get to level 25?

Anyway, if it took me 75 hours to get 1% of the way, that would mean it would take me

99x75hours to get to 60 = 7425 hours from 25 to 60

I highly doubt this is the case, but was hoping someone could shed some light on this.
