   | stats
   count(*) as invocations,
   pct(@duration+greatest(@initDuration,0), 0) as p0,
   pct(@duration+greatest(@initDuration,0), 25) as p25,
   pct(@duration+greatest(@initDuration,0), 50) as p50,
   pct(@duration+greatest(@initDuration,0), 75) as p75,
   pct(@duration+greatest(@initDuration,0), 90) as p90,
   pct(@duration+greatest(@initDuration,0), 95) as p95,
