It is unfortunately common that some doctors set the Min Pressure setting too low or leave it low (like 4) for longer than a few days or weeks. Your Min Pressure of 4 is very low and most new users will prefer the Min Pressure setting to be raised to 5 or 6 or higher within a few hours or days or weeks of starting CPAP use.
I think your problem is that your Min Pressure (4) is too low and is not letting EPR work to help you inhale fully.
When the Pressure (meaning IPAP, the pressure which the machine is using during inhalation) is above 4 the machine will lower the pressure used during exhalation by as much as 1 or 2 or 3 (depending on whether the EPR is set to 1 or 2 or 3), but the machine will never lower the pressure below 4.
If you raise your Min Pressure to 5 or higher, your EPR setting (which presently is 1) would always be able to lower the pressure when you exhale. And when you finish exhaling and start to inhale, the pressure would return higher, which would help you breathe in more fully.
You are sometimes feeling EPR helping you to breathe in and out (when EPR drops the pressure, it helps us breathe out, and when we start to breathe in, the EPR ends and the pressure raises back to the normal IPAP pressure, and this helps us breathe in), but you feel it helping only when the machine has raised the pressure higher than 4, because EPR cannot drop the pressure lower than 4.
Actually, it sounds to me like you would probably benefit from raising the Min Pressure setting to 7 and raising the EPR setting to 3. This would support breathing in and out more deeply.
And if the Ramp feature is enabled, I suggest turning it off.
However, I suggest raising the Min Pressure setting and the EPR setting gradually, not all at once.
For example, tonight you could turn off the Ramp and raise just the Min Pressure to 5 and leave EPR at 1.
If you find that feels better and you like that, the next night you could raise the Min Pressure to 6 and raise the EPR to 2.
If you like that even better, then on the next night you could raise the Min Pressure to 7 and the EPR to 3.
Both the Min Pressure setting and the EPR setting are usually considered merely "comfort" settings which the user should adjust to whatever is most comfortable. However, usually, forum members recommend making only one small adjustment (to only one setting) and then leaving the settings alone for at least a week before considering another change. This is good advice in general, especially if raising the Max Pressure setting (which you would not be changing) or if raising the Min Pressure setting or the EPR setting (which you would
So, be sure to slow down (stop increasing the Min Pressure or EPR) if the changes in settings make things harder or worse.
And please take a look at your sleep data in SleepyHead after each change.

I use a Resmed S10 Autoset 4-12 EPR 1.
Sometimes ventilatory support is active on this engine and helps me finish my breaths. There is a breath that ends my inspirations (I can not finish it all alone). This breath is small but significant, and without him I can not breathe fully. When not, I feel like a junkie in the morning, with enormous fatigue signs. Except when it appears, I feel very well. To make it appear, I have to breathe hard and deep. However, I feel that breath only 1 out of 10 times approximately.
I know that this machine is not supposed to have ventilatory support reagent on respiratory rate, yet I'm sure that aid is sometimes active.
Did someone already feel the same fact? Is there a way to activate it each time?
Thanks, have a good day
