The nosecone may affect maximum performance, but landing with the auto nose cone position on or off on final at the same speed should not make a difference in AoA.
And I must say that I've noticed some performance issues after reloading too. And that was after I learned about the nose cone switch. I find it hard to identify, let alone quantify, so I didn't report it.
I think it's definitely a good idea that a dev takes a look at the OP.
