OP what if the said gambler continuing winning in that 1 hour he or she spends their, is it also advisable for such gambler to retire for day, let's say that it is advisable, will such gambler accept to go for the day when he or she knows that everyday is not a lucky day for a gambler, setting an amount for the day as a gambler is very excellent, this can only happen when a gambler is not always winning because as gambler if you make fortunes, you will like to target high unless you are this kind of person that is contented with what you have gotten so far, but with what I know is only few gamblers that are disciplined, avoiding too much expenses can only be done by a gambler who is not an addict, he or she will have to develop a habit of self control to maintain this decorum.
You imply that there is such a thing as luck, but that's a sphere of superstition. If you set yourself a 1 hour limit, then stick to the limit and enjoy your profits. Making assumptions that you would keep winning after that 1 hour just because you feel it's your "lucky day" is based on nothing more than wishful thinking. Stay disciplined.
That's assuming that hypothetical winning streak is not due to some glitch that shifts the edge to your side, in such case it would be a whole different story.
