@zachdecook yep, me too; I didn't know till a few days ago that it existed and I'm delighted to hear it does! Also the modularity of p-o-s (as well as wvkbd, I presume) makes it so convenient to tweak just the algorithm without worrying about designing the keyboard itself.
Just a thought: maybe the swipe input varies also depending on whether we're using p-o-s vs wvkbd? I just took your default qwerty keymap but maybe I should see if that needs tweaking.
