You can't just count the days. It's the type of riding. The places he mentioned have big mountains. He was also talking about aggressive tree runs.
All of them being trips, I'm sure he took full advantage of the mountains he was visiting meaning little to no cruising.
All my assumption from what I've read of course.
As for the malfunction, it sounds like wear-and-tear actually. Ratchets and straps wear out fairly quickly compared to the rest of the bindings. This is because we are constantly cranking/unstrapping them. So it's expected to wear faster. This is the very reason why I always tell people to ask for spare parts when they get bindings.
If his chasis, highback, or even mounting plate blew out, then I would call it malfunction. All signs point to wear-and-tear to me.
BTW: I'm sure KillClimbz can do to his entire equipment in one day what we can do in multiple days. So the lifespan for his gear is probably much shorter than ours when you count just the days.
Leo, I put in over 60 days per year at a western resort, with bowls, trees, bumps, rocks, and elevation, and my bindings function at least two seasons. Bachelor is no midwestern "hill." I usually replace them out of wanting something new rather than from them being broken. I'm up to 50 days already this year having started on Thanksgiving. That's only 12 weeks ago. I'd be bummed if my binding only lasted 12 weeks.
Edit: I pulled up my stats for this season on the mountain website just for kicks.
482,869 vertical feet total
10,974 vertical feet average per day
23,150 most vertical feet in a day
366 total turns
With the season running through May I might be able to hit 1 million vertical feet this year.
