20 episodes in a single day is a slog, even for a show you like.
Unless you're watching a dub, you can't just listen, you have to be watching the whole time otherwise you miss the sub and have to go back - so you have to be giving your full concentration.
Personally I find it quite hard to my full concentration for more than a couple of hours - nevermind the 7 hours it would take to pull this off.
I will often start a show I want to see the action on in dub, but the first picosecond of voice I hear that I don't like I immediately switch to sub. But most romcom stuff or anything that isn't a mecha or flashy action anime I just start directly in sub.
