I totally get what you're saying here - especially the low ratios of accidents for a particular operator. But, the way that I am thinking of it is that the true measure of the integrity of an operator is how they behave when something goes wrong. And, from an absolute newb lens, I see several suspicious things here - namely a camera being cut, a missing SD card, and 3+ hours to deliver a tank for inspection.
I'll drop it, but I could see value in manicuring the outright suspicious behaviors of operators and presenting the data in a way that allows for others to make their own conclusions.
