Continuity mistake: At the start of the light cycle battle, a blonde haired program says "you've got no chance, user, their bikes are faster than ours" the shot breaks to a wide angle and in the same voice we hear "use the levels" but it's one of the other programs with dark hair left standing with Sam as the blonde haired one is riding away.
Answer: Going by Clu's behavior and personality in the film, Clu's idea of a perfect system was likely a system where every component worked as intended and as expected. One where every action by programs could be consistently predicted. The Isometric Algorithms very existence went against everything that he believed was "perfect", in that by their nature their actions could not be predicted. Users also seem to exist in contrast to Clu's beliefs as their human emotions cause them to act irrationally and erratically.
