Just to be clear, we all agree he's not training properly though?
IMO what he shows us is how you can have all these resources and work so hard and still get it wrong.
I'm 100% sure if you put sirpoc's brain in floberg's body and forced to live floberg's lifestyle outside of running, but the training is planned and performed by sirpoc, then 2:30 would have been broken in Fall 2024, or Spring 2025 at the latest, and he'd be sub 2:25 by now.
Though I used to criticize Jeff Cunningham, for all I know he is giving sound advice. Floberg has documented himself repeatedly straying from Cunningham's instructions. NSM is not his only way to improve. I've even said that John Davis would get Floberg out of his plateau (Davis, btw, is coaching Alec Blenis now. IDK if Blenis has been mentioned in this thread but he's yet another bodybuilder going after a sub 2:30).
As far as Floberg as a coach, I hate to say it, but I wouldn't be surprised if he's effective at helping completely clueless novices running 4 hour marathons down to low 3 / sub 3 marathons, at which point they can actually enjoy running, which isn't a bad thing. Like people learning to sing well enough to enjoy karaoke. A lifetime of improvement isn't necessarily the goal, though some go on to do that.
He can also dispense advice much better than he can set an example. His flaws aren't all lack of knowledge.
Ultimately, he's a very social, emotional, and hard-working guy. While all three of those traits can be used to get better, they can also hold you back. Currently he's on the wrong end of all three of them and he can't see it.
If this race goes poorly for him after he's made it unequivocally clear that he believes he can run sub 2:30 on Monday and he foresees no possible excuse for failing, I hope he finally makes some real progress in his post-race analysis. He does seem to at least try things (increasing mileage, speed block, strength training) to get those last few minutes. I'm sure he'll plan to attempt some kind of adjustment going forward, either mentally or in his training.
