Is it just me, or do others put in quite a bit of extra time for Baseline P6 Schedule & other P6 Schedule Submittals. Never had a position where you get overtime, I think maybe I figured if I was more efficient maybe I could have go it done in regular hours - but that is BS, it takes longer than most people would assume or estimate. I would say now, after too many all-nighters, I always go for less line items, but often the spec forces high, even un-necessary detail. Any rules you live by to avoid this? I've tried scheduling the scheduling but then that takes time away from the scheduling. I thought I was doing ok on my last Airport schedule, then the wind changed the day before, runway usage changed, and it had to be re-sequenced with no warning - always something.
Extra time put in developing schedules

There is a misconception among some schedulers that to track activity progress long duration activities must be divided into many segments. This is a common cause for excessive number of activities to be updated.
If the activity is a duration type such as concrete curing then by reporting elapsed duration then progress is correctly assessed. But progress of most activities is related to physical volume of work. If the activity is productivity type then by reporting production then progress is correctly assessed. Remaining duration will be calculated taking into consideration activity production rate and remaining volume of work.
Activity durations shall be dictated by what it takes for a better schedule:
Unfortunately this is not well understood by many of those who claim they have the absolute knowledge and embed it into the infamous “Best Practices” that prohibit what otherwise would be BETTER than "Best Practice”.
Only a few among available CPM software provides for production type activities as Spider Project does, for decades it has been embedded in linear scheduling models. Not surprisingly in linear scheduling model many activities are of long duration.
Linear Scheduling Method
Linear schedules can be modeled using SS+lag and FF+lag between overlapped activities activities, even if your software does not provide for productivity type activities.
consider the alternative no work at all.
