Well you seem to be more of an expert than people who have more experience dealing with bp's so why do you even bother coming for advice honestly and not even take the advice given to you?
Advice you clearly need when you yourself admittedly say you dont have much knowledge on the matter.

Its not that we are annoyed dont get me wrong, we just dont know what else to say mate. We have told you a number of reasons/answers to your questions but instead you just choose to challenge them, even going so far to wanting scientific proof.
These answers you are getting are passed down knowledge from professional breeders who have been dealing with bp's for many years, they are the science. They have studied through experience the behaviour pattern of such snakes for many years, so why question that? You are not getting another answer from here trust me, we all follow the advices/practices given by the professionals who know what they doing. You think they quess that you need to leave your snake alone for 2 weeks before handling it after a regurgitation? no they know this through experience.

We are only trying to help and educate you on the matter mate, simple as that. Now if you choose to not follow such advices given then I must say you're gambling with your snakes life because you choose to go for what you think is right and ignore practice done by professional breeders. If that is the case we cant stop you, but its your snakes life on your hands man.

But again to clear things out.
-After a regurgitation it is advised not to handle your bp for at least 2 weeks. You may ask why, well this is advice older breeders tell us in the caresheets. Its because the snake after regurgitating will feel stressed and ill due to stomach acids left in the stomach not digesting anything, this causes them to grow weak as well and possibly go on a hunger strike for months if they dont calm down, this is why its is imperative that you let your snake calm down after a regurgitation. How do they know its 2 weeks at least? well trial and error, many breeders before probably handled their snake in less time than that after regurgitation and ended up badly, and have concluded that 2 weeks minimum is at least needed for no negative results. This is completely spelt out for you here, I hope you get the point.

How long should a bp be handled?
Bp's are easily stressed out, even though they may not seem stressed out, most of the time they are, 90 percent of the time they want to stay hidden and feel secure. People who buy them for display or lots of handling, bought the wrong type of pet. The less you handle them the more clam they will be, though don't get me wrong, it is advised to handle your bp once a day at least to familiarize yourself to it and have it be used to being handled, though only for a certain period of time a day is good for the snake, longer and the snake might get too stressed, on top of that probably not meeting its humidity and temp needs while out of the enclosure. 15 minutes max is advised, any longer and you're just stressing the snake out. Again how do we know this?, from experience and knowledge passed down by people who have dealt with bp's for many years.

You say you dont have the "need" to handle your bp, then it should be easy to leave him alone for 2 weeks for it to calm down.
Seriously nobody is here to start a debate on whats right or wrong method of doing things. We simply care about the health and well being of your bp. And if you do as well, please stop being so arrogant about it and just follow the advise given by people who know what they are dealing with.
