The 23.7% for multi-core are great — but they're accomplished in part by adding cores, which Apple won't always be able to do.
It's the 12.1% for single-core that I'm more concerned with. There's also no surprise here; we already know what the cores are like from the Ax CPUs.

So you can see there's a bit of a downward trend. It seemed to stabilize around 20% for a while, but the A15 (relevant here for the M2 Pro/Max) and the A16 were a fair bit lower in their improvements.
Now, the M3 might be different, if it uses A16 cores but at 3nm, e.g. by running them at 4 GHz, or by adding a lot more cores.
Like I said, nothing terrible, but I'm hoping Apple has significant design improvements up their sleeve for the A17 or so.
