I suppose you have less Electron apps open :) I'm using 12 Gb now (1.53 in swap) with Firefox and several communication apps open. Fortunately atm all my works is in Terminal.
MacOS treats unused memory as wasted memory. It does its best to keep memory filled. So a lot of that 12Gb is likely to be 'just in case' stuff. What does the memory pressure graph look like in Activity Monitor?
The thing is, when I run an applicaion that allocates 8 G on top of that, it compresses like 7 G, memory pressure turns brown, it goes 3-4 G into swap and sometimes the app crashes :)
So the legend has a grain of truth, but you can only stretch it so much.
Thing is, when I have 3 or 4 Electron apps open, they are still not using 100% "real" memory - it's all compressed if the need arises. What other apps that you use, use Electron?
