Question: Worst case scenario Vs Realistic Scenario

[devszr]

I was wondering if testing a report under the "Worst Case Scenario" would be good enough if it has multiple pages. Since only the first page of the report is generally displayed in the Chrome window that gets opened, would that be enough to load all the data in a report created with "Data Import" and no live connection to a backed DataSource? Would the % utilization shown by PowerBi-Embedded Metrics be a good way to determine what sized SKU would suit our needs best?

Thanks.
