I can't say in terms of it adjusting or not. In theory RNG should be the same regardless, a fresh chance every time you try a battle again. But there are a number of timers in the game: one that ensures daze happens at least once every five battles, for example. So if you happen to be lined up with one of those, yeah, it'll be a bit tougher.
Really though, this one's on you. No game should ever be played on a single save.
