First, please don't purport to tell me what's complicated and what isn't. I understand a little about this! "Average game, with average rules, and a normal betting ramp [whatever that means]" will get you ridiculously wide estimates. You don't even supply the count, the number of indices you're using, or your acceptable ROR. Why would you think $26/hr. was too high? "The guy" probably used CVCX, while you seem not to want to--or don't have it.
In any event, if you really think you can find a 5/6 game, which surely ISN'T average, your win rate is very close to what you were told.
Now, next time around--if there is a next time--ask a specific question, furnishing every possible detail about the game and the way you play it, including what you had for breakfast (!), and I'll give you a more specific answer.
