Filters vs. segments

Hi Google,

 

I am reaching out you regarding discrepancies on figures depending on whether I use GA segments or chart filters in Datastudio. The segment and the filter are based on a custom dimension.

 

Here are the figures:

Total number of sessions for this view in GA: 2,208,320

Total number of sessions for this view in Datastudio: 2,208,320

Total number of sessions using a segment in GA: 748,828

Total number of sessions using the same GA segment in Datastudio: 753,269 (Okish, sampling)

Total number of sessions using a filter in Datastudio: 667,674

 

The GA filter and the Datastudio filter are made the same way:

- GA segment: Market exactly matches XXX

- Datastudio Filter: Include Market Equal to (=) XXX

 

We get the same kind discrepancy whatever period of time is chosen, and with other custom dimensions

 

Thanks for you help!
