3+2 is a lot of time to input the moves several times over and prepare coffee in the meantime. Seriously, it's not a slightest problem for a competent online blitz player.
OTB cheating: there are many possible ways. The simplest one being having a script reading the moves from the live broadcast and feeding them to an engine and then sending the info to the player. Hans' strength magically decreased in the Sinquefield cup once broadcast delay was introduced for example.

So you discount a possibility that the controversy and allegations against him had at least some effect in him playing worse in the Sinquefield Cup?
Anyway, there were studies out there that there were no statistical differences in his rating gains in tournaments broadcasted with delays and without it. Study by Kenneth Regan also found no irregularities in his play, so the only 'evidence' of him using computer help are allegations by a company that is in business relationship with Carlsen, and his 'bad' analysis in post game interview. I'm not very impressed.

It is exactly the opposite of what you claim: there is a massive statistical aberration in his performance of broadcast tournaments vs. non-broadcast. He is 200 Elo higher in the former.
Because I have seen these claims you are referring to and they were refuted by a more full analysis. This is a carefully doctored result that took only a slice of data 2019-2020, and if you look at a bigger picture, which is actually in a reply to a tweet linked in the post you are referring to, irregularities even out:
Well, I'm probably into it because I don't believe in presumption of guilt over vague allegations. Also, someone is _wrong_ on the internet, you know.
What is happening is nothing but bullying, Magnus is using his popularity and fanbase to destroy am opponent and his fans are like a mob on a witch hunt who are out for blood, demanding severe punishment. I believe it is unfair and an aberration of sports conduct and my ideas of justice. Just crank up anti-cheating measures to 11 at the next OTB event, and see how Hans will play.
That's not a "more full analysis". It's a) not a statistical analysis, b) not "more full" as it's covering a totally different time period rather than being a superset, c) I don't really understand why the "Tournaments" and "no live games" section have totally different columns.
(Oh, haha, 2 out of the 3 tournaments under "no live games" from that tweet are in the small set that the chess.com report says merit investigation.)
Yet earlier in this thread, you were incredulous about even the possibility that a chess game state could be entered into software or communicated during play. Which is clearly a ludicrously blind statement. So pardon us if it's hard to be particularly impressed by, well, whatever you are impressed or not impressed by. Because you don't seem to have much grasp on the basics involved, here.
This statement came from an experiment I conducted. I just tried playing lichess 3+2 game while running a nearby chess.com/analysis on a second display. ...
... and I was barely keeping up with all the clicks, and in the endgame was unable to keep up. So no, efficient cheating in fast games requires at least a special training, and better some automated software to keep up with the moves and to communicate best moves back to player.
I don't claim to have great cheating skills, yet, I'm pretty sure that doing such operations while streaming is very difficult and would be easily visible to the audience. They likely require an assistant or some specialized software.
