Edit: I believe this does both, Mincer, but if you believe otherwise please delete the whole post or let me know and I will do so.
There are also a lot of posts on the pickup makers forum that seem to mirror a lot of the narratives that he brings here. (Sorry to refer to you in 3rd person, thanaton) There's a profile there named Antigua who says a lot of the same things, and was recently banned from mylespaul's forum for combative, "prove it" and "gotcha" style posts but regardless of the similarities, it's the same type of sentiment.
And to be fair, if you're educated in the science of it all, it is very easy to slip into the methodical explanation of all of these characteristics. The textbook says "these are the rules for a coil/magnet/etc." and you can simply apply them at face value.
But for those of us who have the field knowledge, we have seen time and time again an engineer say "there's no way you can hear the difference" and the artist says "I can hear a difference". Often times if an engineer is humble, willing to listen, the artist can show them "See? See when I do this and that how it doesn't respond the same way?" And then the engineer realizes that there is more to the story.
I'm not talking about defying the laws of physics with unsubstantiated snake oil. All it means is that you haven't designed a test method that can produce the delta. Countless times I've worked with an engineer who said "that's impossible, it doesn't show up on any of my test equipment" and the answer is, you're not focusing magnification onto the right set of circumstances.
I work in the industry and am bound by multiple confidentiality agreements because companies don't generally like to outwardly train their future competition. There is an entitlement mentality that believes that all information belongs to me, I should be able to Google anything I want and get the result. If the answer is not provided by the DIY community then the company or researchers should disclose it when I ask for it, otherwise I can nullify their claims as marketing lies and half-truths, or say "if YOU don't know why, then why should I buy from you?"
To go back to an earlier concept in this thread, with regard to how the different gauges or insulation thickness lays down onto a coil when wound with the same number of turns per layer, or altered so that the physical distance between each turn is matched...that information doesn't belong to you until you've wound enough pickups to possess the information, or someone was kind enough (or foolish depending on your perspective) to share their findings. Even then, you won't know if their methods are valid.
The reason people trust me here (and I'm very greatful for that) is because I've made and released products that validate my claims. I've told people that a certain pickup will do a certain thing, and I've been right about it, time and again. That hasn't meant that everybody hears it. Some will say "I tried it and didn't think it sounded different" and presumably they're correct for their rig, or their ears, their playing style, etc.
In contrast, some who debate the theoretical have told people something is NOT audible, and forum members are telling them it's false because they have heard a difference. That makes you wrong, even if the person has no idea how to explain why, and you can crush them in an internet argument based on other people's research.
So to the nuances of wire gauge/type/lay/insulation thickness/etc? Look at it like this: on paper, a 59n with A2 should sound like a Pearly Gates neck, but it doesn't. But they're both 42AWG plain enamel, right?! Wound to WELL below 1dB of difference anywhere on the spectrum. Pole pieces? On paper, a Full Shred bridge should sound just like a Custom 5 but it doesn't. Layout? A PCB tube amp should sound exactly like its point to point wired predecessor, but it doesn't. Or maybe it does, but ONLY after you change a few things around to bring back the nuance you had in the original.
