Interfering float is given by \({F_{INT}} = {F_T} - {F_F}\) = S j Independent float is the time by which starting or finishing of an activity can be delayed without affecting the total float of its proceeding and succeeding activity. Independent float = Free float-Tail event slack 3. What's included. Also compute the free float (FF). Project managers usually apply schedule adjustments to develop an efficient CPM schedule. It is thus equal to the head event slack. interfering (shared) float d. A project can also have negative float, which means the calculated completion date of the last activity is later. The network diagram for a project is shown below. Highlight the critical path. Formulas for calculating Total Float and Free Float are as follows: Total Float = LS – ES (it is also calculated by LF – EF)Free Float = Lowest ES of successors – EF.
