What happened?

For all page performance reports we additionally provide metrics for the highest and lowest value occurred.
Those metrics are calculated correctly when generated for non-aggregated reports - like normal day reports.
As soon as data is aggregated - like for month reports, the metrics are summed up instead of calculated with the correct method.

What should happen?

Metrics should be correctly calculated

How can this be reproduced?

As the metrics are only available through API, this can't be easily reproduced in the UI. It's though visible in certain tests, where the metrics simply don't match.
