CPU Time vs Usage (ani.social)

I'm self studying for a server+ cert and ran into this paragraph. Am I right that CPU time is a set of ticks utilized, the CPU Capacity is the total capacity, and the CPU usage is the percentage of ticks:capacity?

I have been making notes from this chapter, and the more I get into it the more I seem to find things like this that seem slightly off.

Does anyone have a physical copy of the 2ed McMillan CompTia Server+ study guide I can compare against? I feel like someone is messing with me.

Try elaborating on what "CPU Capacity is the total capacity" means and I think that'll get you the rest of the way to understanding this topic.

Above it says that CPU usage is the total capacity of the CPU to perform work. When I say CPU capacity is the total capacity, I mean in ticks or seconds, depending on the measurement.

What I'm struggling with is that the text says that the CPU time is a subset of the usage expressed as a percentage. It seems to me that it is incorrectly identifying CPU usage as CPU capacity.
