That's a good one Tom, shouldn't get too fixated on the small curve deviations, most non turner observers will not detect it, especially as it only shows in profile which is rarely the the viewed orientation.
Anyway it will probably move around to suit itself over time :lol:
The important thing is to get a quantity of reasonable items of the lathe so that you get more comfortable with it and your own techniques, IMO worrying about finite form etc. can sit on the sidelines for a while until you have filled all the relatives and friends needs for useable items.
