Number of experiments completed in the last 12 months, or typical annual volume?
completed = reached a readout/decision, not just launched
experiment = an A/B/n, Multivariate or quasi-experiment (geo/time/switchback/holdout) with a clear control / non intervention baseline running alongside treatment variants - not a 'before and after' test.
Exclude any A/A tests, QA checks or dry runs with no decisions involved
