With this post I should be reaching level 5. Yeay!
I plotted level vs log(score) and it looks linear at level greater than 5. I get level =0.65*ln(score) +1. If I score at a linear rate (equal to my average since joining this site), I will reach level 10 in 36 years or so. If my posts are so great that they keep generating points, making the score an exponential function of time, I should reach level 10 in 16 more days!
Who could argue?
The admins I suppose!
