Most people will learn two handed shooting with their dominant hand and eye first, and maybe dominant hand only shooting. I'm not going to say that training strong and weak hand and eye is a bad thing--it's very good actually. My concern is that you are trying to learn how to shoot four different ways at once. In my experience, it is generally easier to learn one thing decently well, before taking the next step. That's not to say some variety isn't necessary, but I would try to get good at one or two stances first, then branch out.
50 rounds every other day is more than most people will manage. I'm envious! Now, just make sure you are doing productive shooting and aren't ingraining bad habits...for that, I'd recommend some professional quality instruction.
