Not at all. I've just heard experienced climbers say it consistently so I took it for granted. This is the first time I'm seeing actual data on it. Proves the point that without data we just have opinions, not facts.

I've always known that most accidents happen on the descent but this proves the opposite. Can anyone shed some light on this?

Agreed. And climbers are encouraged to use redundant systems of safely so that might be a factor too.

Climbing lingo can be easily misinterpreted by non-climbers. Saying "nice rack" to a dude is perfectly acceptable, for example.
