Just a heads up, I think there's an error in the description next to the graph estimating work time.

I'm seeing this message:

>>> Total is expected to be about 22.3 days.

>>> * likely to be greater than 15 days (p = 95%)

>>> * has a 50% chance of exceeding 20 days

>>> * unlikely to be less than 33 days (p = 95%)

Is the last bullet point correct? Shouldn't it be __likely__ to be less than 33 days?
