Yes, most people here do that using either SleepyHead (free on SourceForge.net) or the vendor specific software such as Rescan for ResMed devices.
Note: The machine they use must be one that collects such data. The other type of machine is un-affectionately referred to as a "brick" since it is just about as smart.

More or less. For the full data machines with the data, part of the data collected is the minute by minute leak rates.
Notice also: That mask fitting is NOT primarily about having it "tight enough" but rather about having it "evenly tight" and to the right extent.
It's obvious that having to tight in one area and looser in another would be problematic, but too tight can actually make a mask leak.

I wanted to optimize it now but doctor said it will be another sleep study so not sure if I want to spend all the money on that.
Some do that. Some use the data to talk to the Sleep Doc or to know when they need to visit the Sleep Doc and to prove they are getting effective therapy.
For instance, I took control of my own settings from day one, even before the first night.
A few people are self-treating and have no sleep doctor.
Others took control after realizing the sleep docs either don't know enough or only see them at infrequent intervals.
Many people just monitor their results and change nothing.
NO ONE will TELL you to change anything but IF YOU DECIDE to change things you will get lots of help.
