Enlarging PRP doesn't always help

Nobody has all the answers and will continue to debate even the subject on port finish (rough burr finish, double cut finish, or even sanding roll finish).
Genuine question, not posing as argumentative or anything negative-have you (or anyone else on here) tested different finishes?

The follow up, and actual nature of my question is specific to the ribbed CNC finish vs a smoothed surface. Have you ever done before and after of flowing a CNC surface, then smoothing it out to see effects? I would suspect that not many people would risk (or pay for) the chance of losing flow…but needed to ask. I have a set of CNC heads and have wondered what having them hand finished would do.

A BIG thanks to all of you for your continued shares of information!!! I don’t see these kinds of discussion elsewhere.
