This is how I do it too.
Re blade length I aim for the main blade to be what I consider about the right length and the tail I don't care if it's long or short
I've stopped caring/noticing where my tie's back blade ends, or which way it's facing.
When you start caring less about these things, so do people around you.
I just make sure the knot is right, and then I move onto more important things in life.
