I didn't enjoy the Magnus Niemann documentary. I thought it made everyone look bad.
In a tournament, pairing rules can result in a player having black two weeks in a row. How big is the tournament? How many weeks?
As far as the scoresheet rules, have you looked at the UCF rulebook? Portions are available for free online.

Keeping scoresheet is covered by rule 15. When time is low, the obligation to keep score is relieved. However, that would also make it impossible for that player to make a time forfeit claim.What I saw doesn't address having someone else keep a scoresheet. My guess is that it is not legal.
Where I play, the stronger player usually gets White in back-to-back weeks, which I think is whack. That’s just my opinion. I like getting Black against higher-rated players—honestly, I [expletive] love it—but let’s mix in some color balance. Why not alternate colors each week, or randomize assignments instead of always giving White to the higher seed? Let me see how folks respond to the King’s Gambit when I’ve got White for once.
