I have to say - it's pretty amazing that's working so well for you.
That's an almost unusable amount of RAM for macOS and doing much of anything - for me anyhow - even just for loads of tabs open in Safari
Yeah....I rarely have more than 3 or 4 tabs open in Safari. I usually close them out when I am done. I don't do that because of performance issues......I just hate clutter.
I also have 50GB available of remaining storage on my 128GB SSD.
