@Scoresby's sibling comment is fantastic. Here's a less fantastic factoid:

I tried not to look at the leaderboard at all. I think I looked at it twice? and then never again. It stirred up a bunch of the competitive feelings that others have mentioned and that I didn't want. Even afterward, I noticed that there was like a dark tide urging me to try to compete. But I avoided that.

FWIW, I'm a super competitive person, though I try not to be bc it's been almost entirely destructive. So maybe others could walk the line in a way that I can't.
