TestFlight - crazy numbers of crashes

Does anyone know how TestFlight counts the number of installs, sessions and crashes? I'm seeing totally insane numbers. I don't understand. Right now for the latest beta it shows me: number of installs "-", number of sessions 19 and number of crashes 36. What's that supposed to mean?

When I look at the individual testers, sometimes there's already complete crap there. For example, there is a user who has reached 1180 crashes in 13 runs. What? Can you imagine a person who runs an application 1180 times and it crashes? I don't.

What's really best, TestFlight gives me almost no crash logs. There were a few from the early betas, but none the last few days.

Do you know of any other tool from which I get consistent information on absolutely all crashes?
