Shutter Count?

Why not quit guessing an look it up?

That's a nice collection of hundreds of completely unexplained numbers you have there, good sir.

1) They don't bother to explain the Kaplan Meier statistic or give any justification for whether it is appropriate here. From what I can tell from looking it up myself which I shouldn't have to do, it is used to shield against right-censored data from people dropping out of studies, but the data we have is both left and right censored and probably has multiple other problems. Nobody claims this sort of thing is supposed to be protected against by the metric as far as I can see.
2) Where did they recruit data from? People who wandered by the site, who are probably super biased to look for a site like this if their cameras died versus not??? The statistic is supposed to be for randomly sampled populations, and I have no idea if this is, because they don't list methods.
3) Why the hell are the graphs all logarithmic? I mean I get that you might want that to show the histogram data, but for survival curve, I live in linear time with my camera...

I bet they would be glad to explain their method right after you explain where you get all your data for all the S.W.A.G. ​info you post.

I don't disagree that my guesses are frivolous and inane.

However, mine is a post I wrote in like 5 minutes on a forum. Theirs is a years-long (?) project with thousands of contributors, dedicated web hosting, etc. Which is why I find it pretty shocking that they still somehow have LESS discussion than I did. Their conclusions are just as frivolous without that discussion and evidence that they controlled for the dozens of problems there could be with this.

So yeah, I'm not saying either of our guesses is right or wrong. I'm just saying that although it has potential, AS IS, this is not particularly a better source of information than Gavjenk's off-the-cuff ramblings.
