Another measure may be derived by weighing the movements differently. The
coarse movements are given less weightage and the fine movements given more
weightage and the dexterity is defined similar to Dm.

Yet another measure can be derived by taking the ratio of the minimum distance to
the displacement histogram defined distance.

Where Lc is the minimum path length. It may be the theoretical path length or the
minimum path length by any of the valid experiments.
