The phenomenon of plateaus in learning is fairly common, and in Go specifically if you look at a graph of how a population of players are distributed in terms of ranks, it has several noticeable discontinuities.
So the Go jump isn't too surprising.
The one with akrasia is, because I wouldn't think of that as something you were learning.
My particular jumps in Go strength came after reading more new theory, trying to integrate it into my game for a while (and failing), and then frustratedly taking a break. I'd come back a few kyu stronger, and games would consolidate this into maybe another stone or two's increase in strength.
This happened enough that I stopped feeling frustrated (rather just stuck) and proactively took breaks. Usually about a week would do it.
