My guess is that the whale moved to WafflePool, since they're at 30.42 GH/s now.
Looks like WafflePool's stats have been steadily improving. Their 10 day average is now better than Clever, although not by that much.
Props to suchmoon for his profit comparison:

4ish horus ago about 10 Gh/s left the pool - anyone know who it was or where it went?

That's "the whale" (
sfire on these forums). He has about 10-12 GH of GPUs and Gridseed miners and he jumps around the multipools according to what's trending higher. You usually seem on Clever, Waffle and a few others, but he got his start on Middlecoin.
