Actually 16-5 isn't necessarily impressive in OWC if you skip fights against more skilled boxers and take those against less skilled boxers. (e.g. a 91 versus an 85).
That's no knock against you, because I have no idea what fights you have taken or turned down. I'm just saying your record in OWC isn't a true indication of success of failure. Your overall rating is a much better gauge.
I agree with Steelernut. Fights are a lot more sim online than before the last change.
EDIT: But OWC is a different animal than regular head to head (which I play). The disproportionate dimensions of height and reach are ridiculous.
