According to the Google sampling documentation, sampling is done based on sessions (fact). In Google MCF queries, sessions are not available as a metric or dimension (fact?) Now I wonder: how is sampling done if there is no metric or dimension for sessions (and date)?
I suspect that sampling for Google MCF is done based on a maximum number of rows of 10.000 for each query. Are there more than 10.000 results? Than sampling is true. Is this correct?
Use-case: let's say I make a query and the "TotalResults" are 67540. Does this mean that I can get all the unsampled data with querying 7 calls (6x10000 and one time 7540 rows)? How do I know which dateranges to query than?
Tried some different approached and found out that the sampling is doe based on sessions and dates, same as the other data from the API.
