Hi Micheal, You have to enable additional tracing categories to get the detailed RuntimeCallStats, see this slidedeck for detailed instructions: https://docs.google.com/presentation/d/1Lq2DD28CGa7bxawVH_2OcmyiTiBn74dvC6vn2essroY/edit?usp=sharing
As for the telemetry tests, I think you'd have to manually go and change the benchmark to add the additional tracing categories. We currently don't distinguish when optimizing/interpreted code is run, essentially this is all grouped under "JavaScript". I hope this helps.
