Then wouldn't that be 0.62*2^256, closer to 2^255 ? Not that it makes a notable difference: at 1 fs per step (1000 GHz, or 1 TH/s), that would take about 4.5e65 years to happen. The universe is only about 1e10 years old...

It would be at least that, with a smaller contribution to the expectation from smaller cycles. That's why I said "on the order of", i.e. not much smaller.
