Confusing TestFlight stats

I'm confused by the stats on the TestFlight "builds" screen. See below.

  1. There are more crashes than sessions. So the definition of "session" can't quite be what I thought. Does a session have to last more than a certain amount of time to be included? Do sessions that end in a crash not count as sessions? Do multiple invocations within a short period of time count as a single session?

  2. The number of sessions falls over time. I.e. once I have released a new version, the reported "Sessions" numbers for older versions slowly fall. Maybe as soon as a user has used version N+1, all their sessions for version N are removed from the stats?

  3. The "invites" column is clearly the same for every version, while it should have been slowly increasing.

Is there any value in these numbers?
