If some quality can be quantified where there's some threshold value that has a significance, then, no matter how close you are under that threshold, the idiom 'A miss is as good as a mile' applies. Implying, of course, that the closeness is irrelevant: below the threshold is below the threshold.
For example, say you had an exam where the pass mark was 60% and you scored 59%: you still fail, even though you were only one percentage point from the threshold.
My question is: Is there a 'positive' version of this idiom, for the situation where you're slightly over the threshold? To extend our example: say I scored 60% and my friend scored 96%; when the quality is banded by its thresholds, we both passed, even though I only just made it.
