you can fix a number for the total float and the filter will display all activities having a TF less than this number...

You seem to infer that all activities listed as being on the critical path must have the same float in order to be a valid critical path. This was never a part of the definition of “critical path.”



Many issues can cause the longest chain of activities to have different float; activity and resource calendars, interruptible activities, start versus finish float, and constraints come to mind immediately. For more on this, I suggest that you review a paper that I once presented titled, “Longest Path Value” on my website at http://ronwinterconsulting.com/published.htm. Good luck!
