If it's a difficult run, your operators will be either be rushed which affects quality, or they'll take the time to do the job right and your price will be too low.
With offset, there's no such thing as 20/20 foresight. The time it actually takes is rarely the time you thought it would. The best you can hope for is to end up in the right ballpark. With the right tools, a very small ballpark. Even the forever-free edition of Morning Flight can help you with that. The program lets you refine the input parameters for each job, then displays make ready and run time when you click the camera button.
Post press and packaging is another matter. There, Morning Flight generally relies on per 1,000 rates, so the time factor doesn't enter into it. I'll be interested to see what other forum members can come up with.

Hi Morning Flight,
The avarage speed of 8000 sheets/hour is mentioned as an example. However It's true that we use it most oftenly for basic, 4/0, 4/4 jobs. When pantone is used, the avarage is slower, because ink mixing and longer job preparation is used. Jobs that are printed 1/1 are, on the other side, estimated with 8500, or 9000 sheets/hour. However it's important to mention that in all these estimations, the time for preparation, ink zone justification, complete "ready to print" process on machine is also included. So, you're right that in some jobs operator gets a "quite a lot of time" to print, but on the other side, when he gets 5/5 + varnish kind of jobs, the avarage don't gets so much better for him, as he would need it. At the end, in this way, you get compensation.
As mentioned in previous post, postpress is where trouble starts.
Looking forward to hear more comments.
