My response to estimating is that if you want anything accurate I’ll need time to estimate - roughly 1/4 of the estimated work should be spent estimating.
As a rule of thumb, if the work is estimated to be a day then is should take me 1/4 day to estimate. If two days then half a day to estimate. If 4 weeks then 1 week to estimate.
We normally continue with guesses that are meaningless.
