The genetic variance in magical ability (at least, independent from general intelligence, studiousness, etc.) is limited to at most three discrete levels. So strictly yes, it’s possible that ‘some Muggles are less magical than others’, but there certainly isn’t a spectrum of magicalness.

Agreed. (I’ve also made a small clarifying edit to my previous comment.)
Everything that you’ve said is correct; I was just confused about what ‘blood hypothesis’ meant until I reread Chapter 22.
