Just catching up on the more recent pages in this thread...
So 1CR deliberately had a difficulty algorithm with wild variation to try to make it difficult for multipools to jump in and out at will, but then the dev was scratching his head and wondering why the blockchain was so unstable, and has now left?

It really is all over the place - staying relatively stable for several blocks, then suddenly leaping from 95 to 5118 in the space of 8 blocks, then dropping back to minimum difficulty a few blocks later (an even more massive change).
I think adding PoS could help, since it will allow the network to continue to carry transactions when PoW difficulty is stuck at a high level. It would also make PoW attacks more difficult. A fixed PoS reward of 1CR would ensure that the supply stays linear, and more consistent (since PoS is far less likely to get stuck)
