The difference between the early start date and the late start date for activities on the critical path is usually the same as the total float.

This statement is true. The early start date (ES) for an activity is the earliest possible date that the activity can start based on the project network logic and predecessor activities. The late start date (LS) is the latest possible date the activity can start without delaying the project finish date. The total float (TF) is the amount of time an activity can be delayed without delaying the project's overall completion date. Therefore, if an activity is on the critical path, its ES and LS are the same, and the TF is zero. If an activity is not on the critical path, its TF is the difference between the LS and the ES. Thus, the difference between the early start date and the late start date for activities on the critical path is usually the same as the total float.
