I had a show last week where I was using multiple playbacks and manual master cue lists. I liked it very well, but I had an issue trying to use the faders manually. The Operations Manual Supplement says "With a cue list on a fader set to manual master, a cue will fire in manual time when the fader is moved from 0% or from Full."
It did but not always on the 1st time I threw the fader. Sometimes it took 1 extra time, sometimes 2 extra full throws of the fader. This was bouncing between multiple cue lists controlling the same parameters (i.e. each list would have a single looping cue moving my lights to a specific location).
