Time Slicing Diagram

[amrear]

Chapter 2 discusses how target latency works and provides a diagram for clarification. According to the explanation:

The target latency is the time it takes for a process to resume execution after being preempted...

Based on this explanation, shouldn't the target latency in the diagram start from the beginning of Process 2 and finish at the end of Process 3 designated by the following image?

It also presents an approach to calculate the timeslices based on a specific target latency:

Timeslices are calculated by dividing the target latency by the total number of tasks.

Suppose we have 3 processes, and the target latency is 9ms, meaning there can be a 9-millisecond gap between the bursts of each process. Using the given method, we divide 9 by 3 and realize that each process can run for 3 milliseconds and therefore must wait for the subsequent processes for 6 milliseconds. This contradicts the definition of the target latency.
