Has anyone done any experiments or know of any data that shows which one is more efficient. Currently I open up my O2 tank for a few seconds in my primary to fill up the head space and shake for a few minutes, then repeat the process. It seems like it makes a difference, but I'm not sure if it's worth the extra effort to use a stone. I use a Better Bottle so shaking isn't really that difficult.
I read in a previous thread that shaking only adds 2.7ppm of oxygen, but I believe that was just using air which only has 21% O2.
