Inconsistencies data between dashboard

[Rohnny]

There are data inconsistency on the dashboard.

On the Traffic analytics, The number of client used Youtube was 4 with usage 435.9 MB

But on the Rule details: Applications - YouTube, It has 7 clients with usage of 599.3 MB.

So I tried to get data directly through API

getNetworkClientsApplicationUsage

, now the usage is 613.852 MB with 7 clients.

Why this is happening, how can I fix or which one is the most reliable real-time data?

Were they set to look at the same time period?

Yes, they all set as 'last 7 days' or 'timespan=60 * 60 * 24 * 7'
