Last time I checked I didn't see any flexing of note, but I will check this again. Having that sprocket so far out definitely isn't ideal, but it never had issues during the season.

Here is the skipping sprocket, and here is the upper sprocket. There is some wear, do you think that is enough to contribute to the skipping?

I also updated the OP with a couple more detailed pictures.
