I know there is a qualitative break between mid power and high power (in fact there are four...levels one thru three, then amateur rocketry), but is there a qualitative break between D and E engines? Or just another power of two?

Other than that, if you can fly a D then you can fly an E.
I've occasionally heard it stated as just F and G, calling E low power. Is that erroneous, or is it a matter of opinion?I always understood it as being E through G is mid-power.
If it's accurately a G motor then it's under 160 Ns of impulse, but it can still be an L1 motor of it exceeds 80 N average thrust or 125 grams propellant mass.Given that, I do know that some G engines are over a certain impulse and can only be launched under an L1 certification.
I don't think there's any official distinction between low power and mid power. I routinely fly E motors in rockets that could only reasonably be called LPR, but also in some (e.g., Trajector) that are pretty clearly MPR. E is sort of a transitional motor class.I've occasionally heard it stated as just F and G, calling E low power. Is that erroneous, or is it a matter of opinion?
But again, it doesn't really matter. The distinction has no significance.
