 The units are counted based on the number of units and the usage time (seconds) of the units, and billed daily. 
 
-For example, imagine you have one Azure Web PubSub service instance with 5 units, scale up to 10 units from 10:00 AM to 16:00 PM and then scale back to 5 units after 16:00 PM. It turns out 5 units for 18 hours and 10 units for 6 hours in a specific day.

 ### How traffic is counted with billing model

+Only the outbound traffic is counted for billing.
 
-For example, imagine you have an application with Azure Web PubSub service and Azure Functions. One user broadcast 4 KB data to 10 connections in a group. It turns out 4 KB for upstream from service to function and 40 KB from service broadcast to 10 connections.
+For example, imagine you have an application with Azure Web PubSub service and Azure Functions. One user broadcast 4 KB of data to 10 connections in a group. Total data is 4 KB for upstream from service to function and 40 KB from the service broadcast to 10 connections * 4 KB each.
 
 > Outbound traffic for billing = 4 KB (upstream traffic) + 4 KB * 10 (service broadcasting to clients traffic) = 44 KB
 
 > Equivalent message count = 44 KB / 2 KB = 22
 
-The Azure Web PubSub service also offers daily free quota of outbound traffic (message count) based on the usage of the units. The outbound traffic (message count) beyond the free quota is the additional outbound traffic (additional messages). Taking standard tier as example, the free quota is 2,000,000-KB outbound traffic (1,000,000 messages) per unit/day.
+The Azure Web PubSub service also offers a daily free quota of outbound traffic (message count) based on the usage of the units. The outbound traffic (message count) beyond the free quota is the extra outbound traffic not included in the base quota. Consider standard tier as example, the free quota is 2,000,000-KB outbound traffic (1,000,000 messages) per unit/day.
 
-Using the previous unit usage example, the application use 6.25 units per day that ensures the daily free quota as 12,500,000-KB outbound traffic (6.25 million messages). Imaging the daily outbound traffic is 30,000,000 KB (15 million messages), the additional messages will be 17,500,000-KB outbound traffic (8.75 million messages). As a result, you'll be billed with 6.25 standard units and 8.75 additional message units for the day.
