Well, these stats look very good indeed, it seems that the experimental pools have already achieved half of the global hashrate.
That is completely wrong!
You have a button there on the right that also includes in the graphs the "Other miners". If you click that you will see the real distribution of mined blocks, not only the top 25 miners.
You are right. Then my previous analysis may still be right, alas.
By the way I've noticed that the experimental pool has stopped to work, at least on my computer..
Yeah, we had 51% attack and now we're working to improve the network for protecting on this kind of attacks.
