That's about right, but here's another way to think of it:
You have a bathtub full of water, and the water must be moved from the bathtub and poured down the sink. There are two buckets available: a green one that is large but heavier and therefore slower to move, or a blue one that's small and doesn't carry as much, but you can use it a lot more in the same amount of time.
