Ok so I was missing this pool in my earlier comment but I'm still confused ... how can this pool have like 4 times more hashing than the overall network (unless that's an overall average)?
The "Network Hashrate" is an average over the diffcutly window, which is many hours.
The real network hashrate is basically identical to the hashrate of this pool, because the pool does nearly 100% of all blocks.
Isnt that a 51% violation??? (Dont get me wrong, I love the pool and am hashing for it like crazy but still...just asking)
