Well from reading the "I0coin - HOW MANY BLOCKS U GOT?" thread it does look like a couple of big players got over 90% of the blocks. Didn't it seem a little strange that blocks were going so fast yet everyone was getting stales? The excuse was that that everyone was getting stales because blocks were going so fast. So if blocks we're going so fast who was getting all the blocks and leaving everyone with the stales?
https://bitcointalk.org/index.php?topic=37608.0Um, no, since stales are work on the old block, it seems that is exactly the effect you would expect when the block are going quickly. Also since the faster nodes are working on their longer block chain faster already, it all again makes sense it played out as it did.
