4 and i am interested in your opinions on its formal (visual, sound) properties as well as numerical properties
I can’t really speak to its visual properties but four is a good number for poetry or lyrical prose because F-initial and R-final are strong sources of consonance. It can’t really be slipped into a sentence as a casual modifier like five or two or seven though, you have to mean it. It takes a long time to say properly, so it demands to be centered by the sentence.
