Substitute "suggesting" with "making wild guesses" and yeah :-)  People could try a fresh start and shoot for a heavier planned landing weight and see what happens.

I just thought it was funny that I never saw it except for one time when my calculated vref 30 was 109 kts, unless newly-installed REX or UT did something.  As a weather engine, suspicion naturally falls on the new stranger.

I don't know how the same airplane can rock or have excursions for one person, and be rock-solid for another, but you always read this kind of stuff in support forums.  I think some of it might be operational.  We tend to do things the same way every time without thinking.  That would be one explanation, not saying it is.  If someone is starting from a saved situation, for example, he might be saving something weird.  That's why I always try to start fresh from the default Cessna, etc.
