Competition federations judge on the combined total rather than any single lift because it rewards balanced strength development across all three movement patterns — squat, bench, and deadlift each stress the body differently, and a lifter with a huge deadlift but a weak bench has a real, identifiable imbalance that the total exposes, even if their single best lift looks impressive in isolation.

Weight class strategy is a real part of competitive powerlifting: some lifters deliberately cut weight in the days before a meet to compete in a lower class, betting that the leverage change and Wilks/GL points adjustment will outweigh the strength lost from a rapid, short-term cut. This is precisely why scoring systems like Wilks and IPF GL Points exist — to let judges and lifters compare relative strength fairly across very different bodyweights despite this kind of strategic weight manipulation.

Training for a total-focused sport differs meaningfully from bodybuilding-focused training: powerlifting programming prioritises the specific technique and neural efficiency of the three competition lifts over general muscle growth, which is why a powerlifter and a bodybuilder of similar experience level can have very different physiques despite comparable strength in the big three lifts.
