How to assess poker skill level?

I play mainly low limit Hold'em ($2/$4) online at Paradise. I play some at casino. However, there are not any real live playing options where is live (Florida). The times i have played live, I came out a small winner. Clearly haven't played enough time to be significant.


I have accumulated approximately 1,000 hours of online playing time and I am even (actually up a few $$)..


QUESTION:


Is win rate in (Big blinds per hour) the only way to assess skill?


THOUGHT:


Due to house rake (3-6 big blinds per hour - say 4.0 per hour)... The average player should lose 4 BB per hour. So I think I am better than average......Here is my table of skill/ win rates....


Highly skilled (5 % of players) --- win 1.5 BB per hour


Skilled (20% of players) ----- lose 1.25 BB hour


Average (50% of players) --- lose 4 BB per hour


Student of game ( 20% of players) --- lose 6.75 BB per hour


beginner (5 % of players) -- lose 9.5 BB hour


========= So based upon a break even win rate......my guess is that my poker ranking approximately 16 % - given 100 poker players (that play at Paradise) 15 are better than me. this be based upon eyeballing the above table). ======== Comments are welcome.....
