Mix

The scenarios a run sends, by weight: one scenario (--scenario=E1), or a mix (--mix=E1:50,E4-state:40,E4-list:10) whose operation i runs the scenario at slot i of a smoothly interleaved cycle (smooth weighted round-robin), so every second sends the same proportions and no scenario comes in bursts. A mix records each scenario's latencies apart, so the writes' latency under the reads (the query bulkheads, the write priority) shows.
