This here is why estimation of tasks (in software) is IMHO futile hand waving. There is always unknown unknowns, snags and hangups which may surprise everyone.
Everybody who actually creates or makes something can agree that that stuff is hard, really hard but oh so rewarding!
the point of good estimation is not the estimation itself (which is not very reliable), but actually thinking about what the details of the task are. I think the estimation should be seen as an excuse to partake in this exercise
