Also, I require high pressure as prescribed. Machine ramps up to 13 and peaks at 20.
If your machine is peaking at 20 perhaps it has reached it max but needs to go higher. Since it is unable to go above 20, maybe you are being awakened by an apnea.
Bi-level models can usually go as high as 25 cmH2O, and maybe you need one of those.
However, the amount of pressure we need is strongly influenced by sleep position. Sleeping on the back usually requires higher pressure than sleeping on our side. So, to minimize how much pressure you need, avoid sleeping on your back.
I wear a teeshirt with tennis ball in pocket sewn between the shoulder blades, to keep me off my back while sleeping.
I agree with suggestion to use SleepyHead to look at your plots of pressure versus time, to see if you are awakening when your pressure is max'ed out.
I think SleepyHead works with your machine as long as the special SleepHead patch is installed for use with '60 series machines. I don't know the details but I think there is a thread which discusses how to install the SH software and how to install the SH patch to make it work with your 560 machine.
