About finding blocks it says:

512,000 coins per block, with a 50% chance(1/2) of finding 1028000 for the first day
512,000  coins per block, with a 25% chance(1/4) of finding 1028000 on the second day
256,000 coins per block with a 12.5% chance(1/8) of finding 1028000 for the next 2 days
128,000 coins per block with a 6.25% chance(1/16) of finding 1028000 for the next 4 days

There is a blocktime of 30 seconds, but we are already mining 128.000 coins/block.

No we are at block 10.048, that should be after approximately 3,5 day: 256.000 coins/block.

What am I missing or not understanding? Premine?
