One thing I remember ( probably incorrectly) from undergrad astronomy is that it takes a photon something like a million years to migrate from the sun’s core to its surface.
Point being: There is very little that we can directly measure from 99% of the sun.
I think the point is that we can’t know what’s going on deeper down, and changes happening there could be a reason to changes in the cycle. No idea if that’s a reasonable suggestion, as I don’t know about workings of sunspots and the cycle here.

Right, but this article is about the 11 year sunspot cycle, which is observed directly by viewing… sunspots. So not sure what your point is here.
