String once bubbled... As a note though, given the report is unable to compare the number of incidents to the total number of dives for a specific grade/depth and so on they arent as informative as they could be.
String
I don't think they can be as informative as this, unless every diver was to log their dives, and such logs were centralised. Some divers don't log em, and they are certainly not collated.
And the stats are not normalised, but with such a small, self selecting sample, there is probably not much more info to be gained.
It would be interesting to see them compared to and other source of incident stats, DAN for instance?
