Deebit being gone probably contributed a portion to that. It was the most efficient pool.
I still see solo shares after some eligus shares; is that a glitch and should go away?

There will still be a small handful of solo shares, just due to how multipool's queue works. I've tried removing solo at various points and stability suffers. If a given miner is being 'bad' (lots of stales in a row with no good shares, or newly connected), it will also receive some extra solo shares so that the 'real' pools don't get mad for multiclone requesting way more work than we submit good shares.
Overall, solo looks to be accounting for <4% of the global share rate. With a ~20% increase in earned BTC, it's still definitely worthwhile.
