I think the method is accurate, but Alonso did not repeat the previous pattern. Sounds strange, because everything is tested beforehand. Alonso had to do something completely different in that turn because he found a new way to reach the limits of the track with the car. How? That's the strange thing.

It boils down to what is I think it's one of McLaren's major roadblocks right now - lack of integration with the engine supplier.

Alonso (or others in the team) had likely run Pouhon flat in a simulator. He, and his engineers, knew it was within the realm of possibility for the car. But, to what level of detail do McLaren's simulations model the energy system? Do they run real ECU code/parameters? Probably not.

If your method does not account for racing drivers pushing the limits then it is not accurate.

Ok, you are right. In an environment where everything is measured and controlled like F1 a driver still can cross the limits. That's what is really weird about Alonso.
