Another interesting thing to note I thought:
I’m seeing these pop up in my feed on Twitter - among people without Boundless, at least from the ones I’ve seen, they can’t touch us. 
One person with 830 in Fortnite, that was the highest outside of what is here for any one game, haven’t seen any of the NMS players hit even 400 yet. That does say something, IMO! 
Edit: Browsed through the replies to this Tweet - of the ones that posted the game breakdown, I’m the highest so far, a couple Destiny 2 players with 900+ being closest (a couple replies had huge overall totals but didn’t see the breakdown on those) - https://twitter.com/PlayStation/status/1217069351918100482
See, to me this is as good an advertisement for Boundless as anything: Almost all of us here blow away the highest totals played for a game by people replying to the official PS account.
