Eric, Task Queue Stored Task Count is updated in "near real" time. Each task that is added to a queue is counted at that time, and each task that is deleted after sucessful execution is subtracted. Task Queue Stored Task Bytes increases as each task is added, but decreases only every couple of hours when a process runs which takes an accurate measurement of real usage.
To estimate the average number of bytes/task, you could pause the relevant queue, then watch the Task Queue Stored Task Bytes change as you add tasks.
