Custom Event Limits: does it allow duplications?

Hi guys

I'd like to know about the limit: "Default limit of 100 custom events per hour, per user"

What does it mean?

Is "100" the total number of all custom events sent?

Or "100" is the number of different custom events( the duplication is counted as one)?

For example
I use the analytics "skill_equip" to know which skill player used in a match. In 1 hour, the player attends about 100 matches, so the number of custom events is 100 (send 100 times) or just 1 (duplication)?

 

It would be 100 separate events
