The whole cracking egg thing is way overblown. For the longest time we poked holes into the side with the air bubble, turns out that didn’t actually do anything either (so we stopped that). It could be that faster or slower heating or the shell makes cracking more or less likely, but unless someone actually (scientifically) tests this, who knows?
I stopped doing the “pokey thing” and have had roughly the same number of breaks at before, maybe even less (one less point to fracture from without the hole). Subjective interpretation of the effectiveness is useless, as we humans are subject to so many possible bias that’s it’s impossible to be objective, no matter how hard we try. You can’t even eat enough eggs to have a statistically relevant sample size, let alone one large enough to determine if it does or doesn’t “help a little”.
You “feel” it helps. That’s ok. Also ok to act on. It’s just about boiling your own eggs.
I‘ve never had a single poked egg break. If I don’t they regularly do. That’s not statistically relevant, sure, but in my personal statistic it seems to work.
I wrote something about this in another comment just now, and while cracks in eggs with holes weren’t frequent, they still happened for me. I have been taught to poke holes in when I was young, and just always did and assumed it was needed. Now I stopped and nothing changed, basically. But it also means I have no point of comparison for how often they used to break without having poked holes, since I just never cooked them like that in the (distant) past.
There’s also no real downside to poking holes either, so why not if it might help. I have just misplaced my hole-poking-thingy anyway, so that saves some space in my drawer and not having to get a new one.
The hole does work too though? It helps release inside pressure from the heating process. I pretty much never have an egg crack from doing the poke and putting them into the cold water immediately. Meanwhile, not doing either one of those things and they almost always pop.
Just because there’s a logical explanation for why it could work doesn’t mean that’s actually what happens, or that pressure is even the dominant effect causing cracks.
Cracks could also come from bouncing around in the water, which could be solved by holding them up in some way. Or it could be weak points/areas from not badly formed shells from hens living in too tight quarters or being malnurished, where buying eggs from more humane sources would solve it. Or a combination, where the pressure differences in the water from rising steam bubbles cause uneven water-pressure on the egg, but they only crack when they are sufficiently weak to begin with, so just putting less water in might be enough to not make em crack (cause then there’s also less water pressure). I could be the packaging, that some eggs develop cracks during transport and they then make them vulnerable, so more local or differently packaged eggs wouldn’t crack at all. As you can see, it’s not that hard to come up with logical explanations and just doing a few things differently might just solve the problem, and even then the reason it was resolved might still be something completely different than we thought.
For comparison: I haven’t poked a hole into an egg in a long time, and I think I had like one or two crack this year. My eggs come from the farmer one street over, and the hens are freeroaming with plenty of space. They don’t get transported at all. Sometimes, I use a steam thingy to boil them, sometimes in water. Even when I did poke holes in, some eggs used to crack anyway, and I’d guess 1 in 3 months in a pretty good guess as to what the frequency was, that’s why I said “roughly the same numer” in another comment.

The pokey thing definitely works. Maybe not 100% of the time but it does work. Keeping them at room temperature also helps a little.

I’m sorry but that’s just mental gymnastics.
