Indeed, saying that changing seeds doesn't improve one's chances of winning we probably must add that it doesn't decrease them either. So, if someone feels good from changing seeds, then why not? After all, this practice can lead to better understanding of the mechanics of provably fair dice game. And getting some new knowledge is always a good thing.
Yeah right, I don't argue with your statement, it's not adding or decreasing anything. If the player/gambler feels like he needed to change
the seed, it's he's right to do so, If he believes that the chance may change or if luck permits him after changing the seeds then so be it
Gamblers always looking for new knowledge, they are aiming to win and establishing system that they can use each time they gamble.
