Why would they care? They want you to drill holes in a little chunk of sky to
kill time. They don't want you flying out of the protected chunk of sky
assigned to you but what you do within it really doesn't matter. You shouldn't
be competing with other aircraft within the circle... ATC will stack traffic
vertically instead of within the circle itself.

Remember, the prime reason to hold is to kill time... plain and simple. The
reason to slow down is only to save fuel since you're not going anywhere. You
could fly around at full speed if you've got the fuel to waste.
