Right. I was speaking about the relative effort increase. For Sec = 0, I have to do 1 unit of work, the attacker 2^59 units of work. For Sec = 1, I have to do 2^16 units of work, the attacker 2^16 * 2^59 units of work. The difference in the amount of time I and the attacker have to do is always 2^59, but with Sec we can change how much work that is.
