| Jun 27, 2018 at 8:04 | comment | added | Erik | I'm not sure if using dice is a good analogy here - one die is more random than ten dice. One die has equal chance of getting a 1 or 6 (a 500% increase), but 10 dice will almost certainly end up between 25 and 45 (less than a 100% increase) | |

Any proper estimate needs at least two things: an expected value and a measure of precision. When we limit to one number the precision gets lost so we can have an estimate for something routine and an estimate for something exotic and new that are the same value. These are wildly different estimates but call them the same thing. Typically what people do is increase their estimate in these scenarios which is a poor solution. You can't blame them though when no alternative is available. | |
