On top of that, it's hard to do statistics on events that don't happen.

I for myself have performed an evasive maneuvre twice last year when the
Flarm indicated a high level alert to head-on traffic. I've seen the
"target" only on turning right after the alarm. Once I just didn't see it
before, once we were both on the ridge but seperated from view by rocks.

Luckily, there are too few midairs to apply statistics.
