There is no such thing as judging muscularity or symmetry by themselves. There never was. The old system was set up to judge the best physique, rather it was quarter turns, mandatories, or free posing. The new system is fine (eliminating the posing round judging), but I do agree with Larry Pepe, it shouldn't be weighted 50/50 between pre-judging and the posedown. I would have made it 75/25, giving the pre-judging the majority of the decision.
In reality, splitting the contest between a pre-judging and finals show is an antiquated system. Why not move pre-judging to the night show and begin with each guy doing his 8 mandatories (as is done now), but let it be a 1 minute free posing routine where all 8 mandatories are shown. Then, do callout comparisons and add up the scores. No posedown.
