Yes, it does. I'm a bit confused as to why you are asking this question though. It's just a ratio and you need enough to immerse the print. Other than that, it's all what you want. I just tone until I get the look I want.
I tried 1:40 first. It was WAY too slow and changes so gradual, I didn't see it change. 1:20 seems to be a good compromise for general toning. If I really want a deep toning (which is rare), I use my 1:5 mix.
