Real Relative Asymmetry (RRA)

Real relative asymmetry compares the RA value of a particular space with the RA value for the root – the space at the bottom of a justified map – of a diamond-shaped system. RRA values will only be needed when comparing across systems of different sizes. This is an empirical way of normalising total depth.
