New Mexico doesn't have periodic motor vehicle safety inspections. My NYS one just ran out. I have a balljoint that needs to be replaced. In NY, it would definitely be replaced before it wore enough to decouple itself because someone would force me to replace it. Here, I could just play idiot until it breaks and blame it on modern cars being harder on balljoints somehow. Except that would be completely irrational.
Heck, before bindings released at all
there were plenty of people that went through a season without breaking anything. That sample is interesting, but far less interesting than the sample that did
break something, and whether or not their bindings were properly maintained. Since we are relatively sure that the system has been working well for decades now, looking at cases where it doesn't work should be quite informative. If the system didn't work at all and everyone was breaking legs left and right, a deeper look at all cases would be in order.
There are some relatively simple truths here, regardless of what you want to believe. The ISO standard makes a guess as to the torques at the interface that an individual with a given age, height, weight, and bootsole length can sustain, and the standard binding properly adjusted and tested does a good job releasing in two axes at a value smaller than that. Every year I see firsthand many, many people skiing in bindings that fail the function and release checks miserably. Jeebus, this year I only worked in a shop for a month and I still saw at least two dozen examples. Many where the owners absolutely should have known better.

I wonder if being around Epic all the time clouds your perception of trends recently? Certainly there are more non-racers in plug boots than ever before, a result of savvy marketing on the part of the vendors. However, the vast majority
of skiers are in boots that would have been considered soft (and short) 10-20 years ago. Even my medium plug is as soft as my junior race boot was back then. Compare, for example, a Diablo Magtastic/whatever to a TNT explosion or Icon. Shorter and
As to the idea that bending of the ski is somehow pinning standard bindings and not allowing them to release properly, I find that very unlikely. Properly adjusted, all bindings have a range of fairly linear spring travel in the forward pressure. The idea of decambering a ski is not new, shape or not. For someone who believes otherwise, the test rig would be pretty darn simple. Put a ski on a bench supported at each end, apply a multiple like 2 of the skiers weight to the boot, complete release test with Vermont calibrator.
If there is a problem with some bindings in that situation, my guess is that it would be remedied by any one of the many floating plates in use for the last ten years.
Personally, I find the problem of pre-release to be more interesting. After all, it is what forces people to use improper binding settings in the first place. If I ever get the opportunity at the undergrad level, I might just embark on a study of that particular issue.

I haven't touched anything with phosphoric acid (or the like) since my accident - no more calcium leaching crap.
Can you point me to a reference on this stuff? I've too been drinking too much diet soda, but I just checked and the stuff I drink uses citric acid. Does that leach calcium from my bones as well? How about beer? Please tell me I'm safe drinkning beer...
