Income ≈ multiplier × (geometric in depth), so depth dominates, multiplier breaks ties. Worth working = the Pareto frontier (no other mine beats it on both depth and multiplier): the deepest is your earner (WORK), the highest-multiplier is the ultimate target, and a mid mine on the frontier is a sleeper that leapfrogs once its barrier breaks. Greyed skip = dominated — a deeper mine already has an equal-or-higher multiplier, so breaking its barriers is wasted.
