If his computer had higher computing power at the time, for example, a block was generated in 5 minutes，Maybe now it is 1008 blocks to change the computing power once
It takes 10 minutes (on average) to mine a block because of the selected target. If it took less time for Satoshi to mine blocks (like 5 min) then he would have simply changed the minimum target to a different value so that it took more time.
Haha, it is true after reasonable inference, but this is just a guess. After all, Satoshi is mysterious in my heart, and no one knows what he is thinking.
