I mean, arguably there is quite a purpose to inbreeding and there are a plethora of examples in commercial agriculture. If you don't understand the genetics and mathematics behind S4+S4-F1 and why inbreeding would be required for such a breeding project, then there is really nothing else to discuss. Notice how I distinguish F1s bred for a purpose with the colloquial term filial one, which is applicable to pretty much any cross that isn't a Bx or S. That would be just about the only way to truly have consistency within a genetic domain, or across phenotypes within a genotype. We can toss around anecdotes and experiences all day, the fact of the matter is unless you're doing things like (1) hunting n=1000 for multiple rounds or (2) S4+S4-F1 or (3) working exclusively with clones......then you are in the same boat as every other pollen chucker or breeder relying on pure luck.
I have a breeder cut from 3rd Coast that regularly dry sifts for 14% of dry weight on a 93 mic screen, that would absolutely blow most 'bred only for sifting and washing' recovery rates out of the water. That is simply luck of the draw though, whether you increase your luck by playing the numbers game or you happen to hunt with n=3 and find some S-tier gas. Both are correct and both have happened and both are happening right now. I chuck pollen every once in a while, I just know I'm seeking out variance not expectation when I am doing so.
"A plant i bred from buttermilk biscuits and garlic storm regularly outperforms anything grown next to it. F1 and quality, consistent plants is possible. There's no need to inbreed them into oblivion." This is like saying you reached a stable point out of the genetic-gravity well of the Z strains by breeding with a Zkittlez, right? garlic storm is rather inbred (and reaps the benefits of such)
