PFI pages seem to be getting hit hard while organically crawled pages seem to get preferential treatment with the new algo change. Especially in cases where INK sees "duplicate content" (and the definition of duplicate content seems to have been extended horribly).
I would stongly recommend that you NOT PFI until Ink gets this figured out. Right now, all the evidence I have says that if a PFI page and a naturally crawled page in INK have duplicate content, then the PFI page will get dropped like a rock.
This is particularly dangerous because now, a competitor (if they know that you have PFI pages) can create duplicate copies of your pages... get them indexed and your site could get dropped and theirs will show up it's place. And yes, I do have evidence of this.

Anyway... the issues I have seen are based on dup content, but I'm guessing there are other filters in place as well.
