Re: France vs Germany
Well, one shouldn't dwell on such irrelevant details, I mean, what was done was, done, next bet.
And it happened, it just happened to me, I had an instinctive urge to bet on France (Olympic basketball semi-finals) but I went for Germany because everything indicated that from a statistical point of view it should be the winner.
But it only lasted a couple of minutes, I remember it now but as an experience, without going into classifications of pain or discomfort.
I think, but I also say it from the documentation I have read on the subject, whether it is any of the situations you mention, they should only last a couple of minutes in those sensations and then just continue.
The bettor cannot stay in that loop of regret or pain, you simply let it go.
