My advisor's advise was basically "find a notation that you yourself like and understand well" and stick consistently to it. He said this in a context of having seen many standard notations before (so he's not saying to re-invent the wheel), but his point was just that notations and ways of thinking are personal. Try to be clear and precise (for yourself and others), but realize that you are crafting something that reflects you and your way of thinking. It's kind of a cop-out, but to be fair it's basically what I would say for programming as well. Try to simultaneously write code that clear to yourself and clear to others. There's no perfect method. Just constantly self-critique and try to improve.
