I believe that the point of “other” is some sort of Black Swan event that isn’t anticipated by his list. By nature such things are difficult to estimate. I agree that the parent’s estimate for this looks way too high. (Part of why humans have trouble dealing with Black Swan events is that they are so rare.) But I’m not sure rounding this down to 0.0 seems good.
