Sorry I missed this reply, but for the record... Yes, you will mine blocks at the same rate you were before the network hash doubling, until the difficulty reset. However, this is still zero sum and the network just beat you. You will mine less blocks now that the network increased even prior to the difficulty reset. The reason why is the difficulty algorithm is block-based not time-based. After N number of blocks are mined, difficulty will then reset itself. You only get that number of blocks to mine at a given difficulty, not a set window of time. Once those blocks are solved, it's on to the next difficulty window regardless of if it took a day or 10. Someone doubling the hashrate the moment difficulty resets will cut your expected return in half for that round as "people other than you" are now solving blocks at double the previous rate.
