Race gas vs pump gas on lower compression street/strip motor

How often have people run pump swill of whatever octane that usually does the job but maybe had issues with its quality or purity causing tuning and running problems over time? More common than not I’d wager. You don’t get those possible issues with race fuel, at least that’s part of its purpose, it is blended to be consistent and the side benefit of having a longer “shelf life” That’s what I read decades ago. Those are a couple of lesser promoted attributes that are possibly overlooked by some that are IMO of more value and actually real vs. the power question.
