I think the value distribution is s-shaped, not inverse-square, so considering we have 100ish entrants for 56 places, the difference between the upper quartile (3 picks-worth) of players is relatively small and down to style and taste; We might also assume that the lower quartile might all be equally useless when playing against an upper-quartile trio, so seeds 26 - 75 have a greater difference in value per seed position than the upper and lower quartiles.
