Well, that's your first problem. You should read it, and you should test your hypothesis.I'm not going to read all that.
I approached you on this topic in good faith. But if you're going to be dismissive and condecending, we can go back to the way things were where I disagree with you and you rant about how terrible I am instead of anything meaningful happening.
You are not going to get an official response (I guarantee it), so I gave you the information you needed too find out the answer yourself. If you want to keep hoping, by all means, but I"m being realistic. You are overthinking something that most likely is not as complex as you are suggesting, and you're implying another Treasure Hunter conspiracy that most likely does not exist.
I do not believe there is any hidden modifier (or even a random factor) to the rate at which TH procs apply. There is no research or evidence out there to suggest that this is the case, so if you think that it is, the burden is on you to find that out, because SE is most definitely not going to tell you. That's just the reality of the situation.
You want answers, but even though you have the ability to find the answers yourself, you're not willing to put in the work to do it.
