chooie,
It might be. But, Mika shows the total of all blocks submited to the proxy.
Dnet stats only show you a total of blocks that are credited to you. Let us say that you send 20 blocks to the proxy. Mika's stats will show 20 but dnet might only show 18. 2 of those blocks where already credited to someone else. Wich means you cracked the blocks right. But someone already did those blocks and they got the credit. Dnet will not credit two different people with the same block. I hope this makes sense.
