AutoSet chasing flow limitations, Response and EPR settings

If I leave the maximum pressure open, then it usually increases to around 11. But my OAs seem to be treated around 7, so I have set the maximum to 7.4 for now. My minimum pressure is 6, and my AHI is usually around 1.

Can the Soft response setting be useful for cases like mine, to react less aggressively to flow limitations? Are there any side effects that I need to be aware of?

EPR solves my flow limitation issues, and it makes the pressure algorithm only increase pressure during deep sleep, but since my brain is tricked into believing that with EPR the machine does the breathing for me, I get a cluster of centrals when transitioning from awake to sleep. For this reason, I don’t use EPR, even on the lowest setting. These are not the usual sleep onset centrals, as I almost never get any of those, and if I get them then it’s usually one or a couple of events.
