If only we could see some other multipool switcher time ... ?

Looking at the graph its very strange, and my inner feeling is that the problem is not with the miners, but with your configuration for the switcher. Something, somewhere is delaying the switch for the miners.

It takes about 3 seconds for the majority to stop mining and then after the first 7 seconds, a new 3 seconds for the majority to mine the new coin. I think we must look closeley what happens those 7 seconds of mining the new coin. Its not that some miners are very slow for the switch, but appears that some miners are Very fast to mine the new coin ?

Sorry if i'm talking stupid things that make no sense.
