I've often found that many often believe things without actually experiencing whatever it is they "believe" for themselves... and that often other people have entire different experiences...
For example "many people believed" for years that if you didn't get the beer off the yeast the day after whatever, it was suddenly going to autolyze and open up a portal to hell or something.... but then other people proved that "what people believed" just might not have been accurate..... that they were leaving their beer for month with no ill affects, and may actually found there beer was better than when they fearfully rushed it off the yeast.
I've said it for years, ask 10 different homebrewers how they do something and get 12 different answers and there all going to be the right answer.
That's why I recommend that people not repeat things as "advice" unless it's based on their own actual experiences and not just something they "heard."
And that they
experiment and try things for themselves. THEN share their own experiences... What works for them. Rather than just repeating the "chestnuts" that armchair brewers repeat ad nauseum.
That's why when I answer questions it's based on my own experiences.... and trying various things...not just parroting consensus...or relying on some "expert" to decide what's right... (John Palmer parroted the autolysis myth for years, along with hot side aeration, until he was pushed and said that he just repeated "what many believed....")
And don't just take my word for anything either... try try try and see what YOU prefer.
If 3 days works for you, or anyone fine... but if you haven't tried other days... like ever tried 7, or forgot about the hops and let it go for a couple weeks, or whatever, then how does anyone know for themselves if it's better, worse or no difference... And if we've only ever done 3 (or 7) then ONLY talk about OUR OWN experience, and not muddy the waters by going beyond our own experience and treat it as the ONLY way.... know what I mean?
That's what comes with experience I think, seeing what works for you... pimping your process (like I show in the bottling stickey.)
And I think that's also how we can be more helpful to each other... not by just repeating things that we've "heard" but sharing our own experiences- and often those experiences may actually be contrary to what the current "party line" might be. By showing NERVOUS new brewers who may believe there is ONLY one way to do something, that there are many "our ways" out there, we're actually I think more helpful.
