| Re: DCI: What could have triggered it? Bad luck.
DCI is essentially a statistical entity. Just because you "dive within the NDL" doesn't mean that you can't get bent, just that it is unlikely.
To be honest that does look like a moderately provocative series of dives with (from a recreational perspective) reasonably deep maximum depths, shortish surface intervals and dives around the hour mark. While you friend is no doubt disapointed to have got bent, the only way to be absolutely certain of not getting bent is to never go diving.
I would ensure he is reviewed by a competent hyperbaric physician in the near future to talk through the implications of his bend.
