names: * = proposed

names: % = not shown on PTS plots

MOS: * = maximally even

complexity = ln(n*d)/4

damage = 1200 *log(n/d) / log(n*d)

(complexity and damage are calculated as in the "Middle Path" tables)

Graphs

Complexity vs. damage plot. z < 1 corresponds to the "Middle Path" inclusion criterion.
