We did some interesting experiments with Go where we inverted the label of who won and measured what impact that had on the final model. This is a binary label so it's probably more impactful (it's the only signal we are measuring)
From memory it had only a small impact (2% strength) with ~7% of results flipped, at 4% it was hard to measure the impact (<1%)
