In your task, you might have some conditional statements. If the condition is met, certain codes or blocks are executed thus take longer time to finish than when the condition is not met. To ensure your task is able to execute in "real time" continuesly, you need to make sure the maximum task execution time is smaller than the step time of the task. In other words, you can only slow down (by puasing or inserting delay), but you can't speed up to make "real time".
