DaasYochid; If you have followed some of my postings here, you will know that I recognize truth when it appears. I did not see yet the Pri Chodosh you mention but on the same page that you brought downe in an earlier posting, you will see from The “Pri Toar” (not sure if it is the Pri Chodosh himself) in se’if koton 15, that he essentially echoes what you you just wrote. He is very adamant about tiny bugs that are present, even if you cannot see them with normal eyesight, that they are “ossur”. So,at least you have some earlier Possek to rely upon about exhaustive bedikah.
The quandary you will have with such an approach is “where do you top?” . A magnifying glass? a small microscope? Half an hour waiting to see that a tiny speck walks? a hard brush to scrape every strawberry? That is why this subject is so fraught with uncertainty if you look for extremes.
