I'm not sure where you're getting 1.06% from? I see a score of 19.1 versus 18.0, so that's about 6% faster. This squares with what I'd read somewhere else saying the 68030 is about 5% faster than the 68020 at the same clock speed, due to the additional cache it has.
On a different topic, I'm surprised to see the CPU performance difference between the SE and Plus in your results. They are both 8 MHz 68000 on a 16-bit bus, and I'd always thought their performance was identical. But I dimly remember something is different about how they interleave access to RAM between the CPU and the video circuit.
EDIT: Apparently I wrote something about that exact topic, 12 years ago: https://www.bigmessowires.com/2011/08/25/68000-interleaved-memory-controller-design/
