Thank you for the details.
You said he had a decompression stop at 30 feet. Was this part of a safety stop routine(some people start them deeper) or was this mandatory decompression? Do you know how much mandatory decompression he had?
If he was wearing a computer this can be very helpful just to see how far in the hole he was(we can all speculate being that he had a 119cuft tank of air, but lets not do that).
