So apparently my pressure is 13. Ive been looking at numbers besides members posts and see various different ones, of course.
You have a ResMed S9 Escape listed as you machine.
This is a straight CPAP machine with which delivers pressure at a SINGLE setting (e.g., 13 in your case.)
Presumably this was "titrated" or measured as the most suitable pressure during your (titration) sleep study (or the 2nd half of a "split study".)

Those of us with an APAP (or other automatic machine) have two numbers, Minimum (or nightly start pressure) and Max (the highest the machine can go.
APAP machines can be set to deliver a single straight CPAP pressure but the other way around won't work.
My machine for instance is a ResMed S9 AutoSet.
Notice how confusing it is that we BOTH has an "S9" -- this is the series number and the AutoSet or Elite is the actual model.
Both are the latest SERIES but the APAP Autoset is a more capable machine.

So in my case, I take it that it would be 13??!!
That is correct.

No, not exactly, especially if you don't need a VERY high number, e.g,. >20. Which may requires ANOTHER more advanced machine.
Some people respond at a lower pressure even though their Apnea is worse, i.e., their AHI number is higher, than some one who needs a higher pressure.
13 is about the middle of those of us who don't need the very high pressures.
Almost everybody needs 7-8 or more or they don't need the machine (not everyone, but maybe the 95%.)

Is it because it helps to make it feel less overwhelming, or is there another reason?
The point of the APAP (auto-adjusting CPAP) is to give effective therapy at the lowest practical setting but increase the pressure as needed.
Frankly, I can't even FEEL 13 (my machine is set to 11-14 right now).
I have to OPEN my mouth and let out a little air pressure to be sure the machine is pumping.
I know that some people find the air blowing overwhelming but just don't understand it (if I am being honest.)
You are not alone -- it's my failure to understand, not yours.
So intellectually it's clear that some people find that more air is worse, it just doesn't work that way AT ALL for me.
The only reason I don't turn my pressure up even more is it looked to me like that might be causing some CA events (clear airway) where we just stop breathing rather than having an obstruction.
For *ME*, more air pressure it better (up to a point I suppose.)
BTW, by default, we are supposed to be letting the doctor prescribe the changes and the DME supplier make them on the machine.
Many of use have just taken control of our machine and read our own data card to review our statistics and guide those changes.
EDIT: Others have pointed out that your machine is a "Brick" (sorry), meaning that it doesn't collect detail data needed and displayed by the following programs:
