I only score a round 10-10 when it's an incredibly slow and tactical round where neither fighter lands anything of significance. In other words, when neither fighter does anything to deserve winning the round.

When it's a close back and forth round with tons of action, I don't score it even, I feel obligated to declare someone the winner of the round.

I'm not saying that's the right way to do it, it's just how I do it.
