Really have to wonder why records like these exist.
In the real world nothing good can come from a bounce dive to 300m+. It is dangerous (I sincerely doubt any decompression algorithm writer will give any sort of assurances about their algorithm that far outside tested limits), there have been numerous deaths in attempts to beat it, and it achieves absolutely nothing apart from inducing more people to attempt it and potentially kill or severely injure themselves themselves.
The reality is that diving that deep or deeper should realistically be done as a SAT dive with chamber facilities on hand (as happens every day in industry).
