The "Time Lapse Factor" is not a standard term used in project planning and scheduling. There's likely a misunderstanding or a different term being used.

However, there are concepts related to time and scheduling that may be what you're looking for. Here are some possibilities:

• Time Buffer/Contingency: This is a reserve of time built into a schedule to account for potential delays or unforeseen circumstances. It acts as a safety net to ensure the project stays on track.
• Time Scaling Factor: This term is sometimes used in software development to account for the time it takes to complete tasks in a project. For example, a scaling factor of 2 means that the estimated time to complete a task is doubled.
• Lag Time: Lag time represents the amount of time that must pass before a successor activity can start, even if the predecessor activity is completed earlier. This can be used to account for dependencies between tasks.
• Lead Time: This is the amount of time that an activity can be started earlier than the predecessor activity. It can be used to shorten the overall project duration.
