Hi,

I use Google Data Studio (GDS) to process some data gathered by PiwikPRO, most values are transferred accurately, but some have a considerable mismatch. Average Session Time and Average Time on Page values show intolerable mismatch:

Is there a way to find the cause of this problem? Is it possible to see the exact formula PiwikPro is using to calculating the average result for these values to be able to replicate it in GDS?

Thanks,  
Alex
