Latency and Time line of data returned by Microsoft Graph Security API

BrittanyRandolph 

For Latency I mean, if there is any time delay between the alerts logged by security provider and actual results return by API. 

I need this information for reporting purpose. For example, if there is an alert logged by provider today, will it be returned by API instantly or after some specific time.

I also need info regarding the time period of the data returned from API for reporting purpose. For example, when we call the api, will the alerts are of last 90 days, 180 days or some other time frame. 

I am actually looking this information for data returned by Power Bi Connector for Security API.
