What's the theory/science behind speeding up towards the end of a dynamic (DYN or DNF) swim?
I've been having a discussion with some freedivers about what I observed when watching the recent CMAS European Championships. The commentator made a few references to this and it could be plainly seen in some competitors swims, mostly DYN, and in one case some guy went off like a rocket and left his safety having to sprint after him.
I'm not well versed on the physiology side of things so that would be interesting to understand. It's been said that:
and also that:
From a psychological perspective, if you are doing this then you are focusing on outcomes rather than the dive and that's not really where we want to be, is it?
It's seems a bit of an edgy thing to be doing, that would require a high level of self-awareness to instigate at the right time and so is not something to be advocated to or practiced by the inexperienced.
I'd love to get peoples opinions on this.

I believe the standard justification for speeding up at the end among those who advocate it is based on the idea (which may or may not be correct) that a short period of intense exertion at the end of the dive will be biased towards anaerobic rather than aerobic respiration.
and also that:
Throughout the dive your dive response only gets stronger throward the end it's Soo strong that your muscles are not supplied with oxygen you are basically sprinting for free...if you go fast at the beginning of the dive then you oxygen consumption is a lot higher because your dive response is still weak
