OT Re: the electrix repeater/estimating software jobs



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.

Back to tweaking loops on a Nord Modular so I can twist the input of 
s sax player friend who is coming by tomorrow.-:)
