I respect the fact that people are connoisseurs of coffee or wine or whatever—you do you, I'm not about to argue for the case that there's an overabundance of joy in the world—but tbh your method sounds like a decent method as it is.
I'm not convinced that specialised lab equipment or scentific methods is necessary for cold brew tbh.
Btw I used to love doing cold brew green tea in a similar way: get a large container, put a decent amount of green tea leaves in it (a smaller nut milk bag that is the size of a wallet or a bit bigger is really good for this, you can get them cheap online) and leave it overnight. Do not remove the tea leaves. When you pour a glass, refill the jug with more water and you can go like that for 3+ days, depending on how much you drink and how much tea leaves you add.
It's really good for the hot summer months, it's more delicate than hot-steeped green tea (that westoids almost invariably butcher by making it overly strong and using overly hot water) but it's nice.
Depending on how much you consume or how big your household is you might want to go for a 1L container or you might opt for like a 3L one. Whatever the case, you can absolutely wring every last cent out of your green tea leaves with this method and it's really minimal effort too.
