It is very odd that everyone's experiences are different with this landing thing. For me, the problem used to be awful (up to 5 or 6 landings recorded), but now I'm on version 3.4 it usually only records 1 landing - very occasionally it'll record 2.
I haven't updated to 3.6 yet (what happened to 3.5?) because it sounds like it's more than just a minor bug-fix. What's the new version like - reasonably stable?
