Just an interesting thought... If using Bidou you can in fact negate all minus-points of Tap-Jump on?
1.: Accidental Jumping when Shield-tilting/ Shield-tilting slower (use both sticks)
2.: The accidental 2.Jump input when using Up-B (just use the C-stick)
3.: The accidental 2.Jump input when using Up-air (use C-Stick + Attack Button (instead of Left-Stick + Attack Button))
And about the up tilts.... no idea about them..
