Correct, but many of the blocks we've hit recently haven't been much over 100%...so if we get one of those, it'll be at least a week to crack it with our current hash rate. And that is what I was getting back with the one block every 36 hours comment.
Prior results have no impact on current or future results! The human mind likes to think otherwise, however it's a complete fallacy.
In other news, difficulty is slated to decrease by 6% in 12 blocks. About 2 hours from now..
