Yes, when you look at it that way, your answer makes sense.
Thanks for clarifying.
Seriously?
When I tell my manager that something will take approximately 2 weeks, he's NOT going to schedule 5 months. What good is an estimate at all if you're going to give yourself a +/- 1000% margin?
Where I work, we are asked at a minimum to provide a Class D estimate, which is a ballpark estimate, -25% to +75%.
My management, in particular, expects that I will have at least a vague clue about how much work is involved in a given activity, and having done similar work before would at least be able to hit it somewhere in the ballpark.
I like to use PERT estimates, or something similar:
estimate = (optimistic + (4 * likely) + pessimistic) / 6
So my 2 weeks (likely) becomes:
(1wks + (4 * 2wks) + 6wks) / 6 = 2.5 weeks
YMMV
You are in a maze of little twisting passages, all alike.
