Hourly rate - realistic expectations

[Magician]

Hi,

I've been making about 20 cents per hand on Pokerstars $1/$2 NL, have a sample size of about 50,000 hands.

Is that representative? Can I expect that in the long term?

What kind of win rate do top internet pros make?

I've heard of people making as much as $300 per hour, but my forays into the big games have resulted in huge swings, I got out of there before taking serious capital loss.
