As a professional software developer currently involved in very
complex video effects software, I can sympathize.
Here is my partly tongue-in-cheek algorithm for estimating a software job.
1. Estimate the amount of time the job would take if nothing went
wrong.
2. Allow for the fact that things will surely go wrong, as they
have in the past, and double it.
3. Allow for the fact that, in addition to the things that have
gone wrong in the past, new things will go wrong. These will be even
harder to fix, so double the estimate again.
4. One of the things most likely to go wrong is the initial
estimate i step 1. Allow for this by doubling your estimate again.
If you work hard, and are reasonably lucky, you won't exceed this
estimate by more than 100%.
Although the above analysis was conceived of as a joke, I suspect
that it would be reasonably accurate at estimating software jobs.
