Hey, our data team would like to know how the data is queries on BigQuery? we'd like to evaluate the costs and I need to tell them the average number of queries that'll be used by GrowthBook for the experiments we send ~80k events from GA4 to Bigquery per day

Pretty trivial costs. I send over 2M a day and i think GB queries cost under $10/day usually. I also have a ton of metrics and around 5 tests running usually.
