BOUNDARIES
Calculation boundaries
The tool uses the official base body-part costs, 3 ticks of spawn time per part, 100 base hits per part, and the 50-part body limit.
Movement assumes a fully loaded body where every non-MOVE part produces fatigue. Boosts, damage, empty CARRY parts, pulling, Power Creep effects, and the real path can change the observed result.
