I don't have any system.
I don't have a style or set time. If I am on line and on here it means my eyes have nothing to do for awhile. I draw and paint so my eyes are my tools and they need a break now and then.
I take 'em as I see 'em. If someone has already said it I can't help that, but maybe they didn't say it the way I did. I often get "likes" days, weeks after I've posted so I know some people are like me, they start at the beginning of a thread.
It may not seem like it reading my typos and incomplete thoughts, but I edit a lot. If it's long and error filled it means I got a migraine along the way and had to bale. (they come, they go...it's when they stay people around me get dead).
I also have worked hard at keeping busy in retirement and that means my days are full and sometimes I am cramming in a response while on my way out the door. In the evening, when I can treat my migraines, my replies begin to wax a bit, drift into new topics, galaxies in fact....that has to do with the medication, my migraines require a LOT, I mean a LOT of THC.
