This pretty much fits into the same puzzle.
Skill is what matters. There are other things, like knowing your opponents for example. But overall, you don't need to know your opponents if you are good enough.
Wins don't matter
Gs score doesn't matter
Losses don't matter
Ratio doesn't matter
Skill is all that matters in the end.

For a spar anyway, making a eye-candy profile? Need those wins and that good ratio!
