I understand the concept of saving the most characters. If you were designing some kind of compression algorithm or something, that's the variable that would matter the most. But from a human perspective, I might be wrong about this, but it feels like there'd be a mental tax to typing this way in that you have to deliberately think about your typing too much rather than focusing on the words. I think it's nice to mostly focus on the words. Even if you get to the point that typing that way is 100% automatic, I'm not sure that this is always a huge win. Imagine being out and about and needing to use a friend's computer for some tasks. All of a sudden, you've got the muscle memory of randomly compressing lots of common words where it doesn't work with the system you have to use. There's a reason almost everybody uses Qwerty keyboards despite there arguably being more efficient keyboard layouts possible. That said, I'm not trying to dissuade you from doing whatever you want and if it works great for you more power to you.
