Service menu to the rescue!

It's so easy to stay in the box, but geometry requires you to think outside of it. Or at least, think in more than 2 dimensions.

I pushed the lower pin further out and made the top match to the point the whole image was pinned, then used the main pin cushion control to balance the lot out.

I think I'm done with this thing. As mentioned on page 1, this isn't a PVM/BVM and even then, perfection is impossible on these consumer sets and really, that's most of the reason I love them.

Thank you all for your help guys!
