Individual Level (IL) runs time a single stage, level, or section of a game in isolation. Full-game runs time the entire game from start to credits. These formats test fundamentally different skills. ILs reward pure optimization: grind one level thousands of times until every frame is perfect. Full-game runs reward consistency: maintain near-IL-level execution across dozens of stages without choking once. Many runners specialize in one format; IL grinders dissect single levels to sub-second precision, while full-game runners sustain high-level play for hours. The sum of all IL world records (the 'IL table') often represents a time significantly faster than any full-game run, showing the gap between segmented perfection and sustained performance.
