I don't know if I agree with you that the daytime slot was key, though it was certainly half of it. I don't think he would have been as successful without the fact there were trials going. His success came down to, in large part, to the fact you could either watch him, or watch some shitty bias MSM coverage that painted Heard as a victim, and Rittenhouse as a murderer. Moreover, I think he realized (correctly) that assembling a panel to review the day's footage at night time wouldn't have worked as well because it's a subject where you need to strike while the iron is white hot. The audience that watched him was the audience that wanted up-to-the-minute coverage. That means doing it live. If he didn't do it, the true crime wine moms would have gone elsewhere and skipped him entirely.
I think this is one of these things where he wants the world to revolve around him, and he honestly felt that his personality played a big role in his success. That if he did something else, people would keep flocking to him no matter what he did. He's overestimating his own abilities, and underestimating the interest people had in the subject matter he used to cover. Maddox is interesting. Weebwars is interesting (some people on the Farms found it lame, but the numbers don't lie). Amber Heard and Rittenhouse were very interesting. Balldos, cooming, and Dick's ridiculous obsession with Eric July, not so much. The numbers aren't lying there either.
