What's the best ratio of coffee beans to water to make cold brew? And how long should it steep in the fridge for?

Thanks! I'm a bit strapped for space lately, so I've been using my French press in the fridge for cold brew. I'll fill it about half to 2/3 of the way with coffee, then fill with water, press down, and let it sit in the fridge overnight. I'll pour it into jars, stir the coffee, refill with water, press again, then wait overnight again. It also helps filter it really well, too, saving me a mess. I'll do this 3-4 times until the coffee gets light-colored then toss it. I like it a bit darker/more concentrated, I'll dilute it a bit with water and it goes further.
