If you want to add something to this thread, either find the weight of FC MT500 spider only, or argue why my estimate say 4 year lifetime catastrophic failure rate is likely more than 2x lower.
If I do that will you pay any attention? Who knows, but here goes anyway, you can't say we haven't tried...

two peope out of thousands who read your thread confirmed your bias
Thousands! I’m doubtful but you may be right. Around 25 unique users posted, according to the 1% rule 2500 users read the thread https://en.wikipedia.org/wiki/1%25_rule_(Internet_culture) but since It’s a question I think it’s probably somewhere between 500 and 2500.
On the first bit, firstly you're misusing the rule - it's about the proportion who lurk relative to posting on a forum in general, not a particular thread. Logically the proportion posting on a thread relative to those reading it is far, far lower than that because there are lots of threads and even prolific posters only post on a fraction of them - I CBA checking the exact stats (do your own research), but it's easy enough to find the number of people posting on here relative to the number posting on your thread - you'll find only a small fraction of the regular posters have commented.
The second bit - please tell me you're joking? You're asking a question about breaking cranks - at which point you have to count not just the lurkers on your thread, but the lurkers on the whole forum - do you seriously think those who've broken cranks aren't far more statistically likely to open your thread and post than the average forum user? Right there you have confirmation bias and serious skewing of your stats.
Though it's kind of amusing that you start by being dubious about it being thousands, but that's within the range of even your guesswork calculation.
I've been a bike mechanic for 15 years now, for my sins. I've seen plenty of prematurly broken stuff. I'm yet to see a broken Shimano HT2 crank.

I've bent a solid crank, can't remember how but the end result was I had to replace it.
It was either Shimano, Truvativ, Bontrager or Firex so you'd better strike them off that list.
Seeing as you haven't considered breaking a crank by bending, you have a skewed result and based on superfluous Wikipedia forum usage stats, I'd wager that there have been more bent solid cranks than cracked solid ones.
The only snapped crank I’ve seen personally was a Middleburn set back in 1996. They were the ones where the square taper was set in the ‘wrong’ orientation & they snapped there.
I’ve seen one or two hamfisted attempts to fit pedals result in knackered cranks & even some cut off when extractor threads have been ruined.
No other snapped ones though. I’ve been riding bikes since before Hollowtech was a thing, I spent 5-6 years in the trade & even on here since the days of dial-up & GoFar I don’t remember it being something that comes up much at all.
I really do, all jokes about you being a bit mental aside, think that you are overthinking this just a little bit.
Buy a set of each cranks you are interested in, weigh them?
Email the manufacturer and ask what their rider weight and power limits are for each product, this should eliminate anything you are over... (I'm not sure if you have mentioned what your stats are)
A third thread should clarify the situation
20yrs + of riding bikes, I’ve never snapped a crank & never seen one. Anecdotally, I’ve heard of maybe 3...including yours.
Its in your head IMHO..

(Have I just missed some irony? 😐 )
EDIT : Yes, clearly, I have. 🙁
Email the manufacturer and ask ...
Maybe he did, and the manufacturer then attempted a huge cover up...
probably higher for me since I’m stronger and heavier than avg.
Well that's nicely counter balanced by your reasoning 🙂
Suggest we ask Geoff Capes for his input, if you are of the same age group as me.
Been biking for about 25 years and never heard such bollox about cranks before.
From an above average weight rider
You could drill a hole in them and fill them with an appropiately strong yet light metal.
I bet you have a 100% lifetime failure rate.
Have you personal experience of snapping cranks?
Have you personal experience of snapping cranks?
Because I don't use approved 'industry standards' combinations on my bike I get lots of pedal strikes causing breakage of the cranks every other ride. I have been using superglue untill now, however they just snap again right next to my repair.
I was thinking of pouring molten lead in, so it will be flexy in the centre with a stiff Alu crust, hopefully this will solve the problem and I will be the go to man for technical help on the internetz.

Let’s give it a rest. Some of this is uncomfortably close to becoming bullying,
I disagree. Don't mistake my stupidity for such.

Sorry, I was not referring to you.
There’s some lovely people on here.
I’m going to poke my head over the parapet here. The SLX crank I broke was the one with the massive bash ring and steel pedal inserts, it looked and felt indestructible so was treated as such and its not really a shock it failed.

I agree.
