DIR has only been adopted by a few.
DIR divers are a very small percentage of divers.
Until there are as many more divers using your system your comparisons are statistically inadequate.
How many people dive?
How many die?
.001%?
You will need ten of thousands of DIR divers, diving for years before your comparisons have any statistical meaning.
Your sample size is not even in the noise of all divers!
