Why add 20%? That's upside precision for something so inaccurate. 2.2x is a good way to set a budget for someone doing a task after it's already been done once

Why add 20%? That's upside precision for something so inaccurate. 2.2x is a good way to set a budget for someone doing a task after it's already been done once by someone else.
The golden rule of estimating is to measure past estimates and use them as a multiplier in future.
The platinum rule is to stop estimating because it's useless.
- bfuclusion 6y agoRight. Estimating before you even know what you _don't_ know is tea leaf reading. It's better to ask the person who wants it done "how much is this worth to you", or "what's my budget to get this done", and then work from there.
- Heyso 6y agoDouble it, then add 20% make a 2.4 modifier. 20*2*1.2 = 48 20*2.2 = 44 // I, also, was confused myself at this point 2 *1.2 = 2.4 // not 2.2
