The discrepancy is probably because Google Analytics API and BigQuery handle data sampling differently. Google Analytics samples your data when it gets too large, while BigQuery gives you all the raw records. That’s why BigQuery may show more data than API. It’s like watching a movie in 4K where you see everything (BigQuery) or in SD where some finer details are lost (Analytics API). You may want to use smaller data segments or switch to GA360 for unsampled data.
