Too much complicated theories and tech justifications for something very simple.
... and I'm being discredited here and there, during the process. No hard feelings about it.
Please, someone have a try.

That would be me  . 

Yes, I'm discrediting you but only in the context of you being human. I've done it myself (thinking the was an improvement where there was none) and I think it's a phenomenon that has to be taken into account in these discussions. After all, we're talking about a 'probability' that is so far fetched, it goes against everything I've learned and, more importantly, my experience in data transmission. 

I've said it before, I don't get involved in discussions about stuff I don't know enough about, however dubious some claims can be, but this one is a no brainer to me.
