ICE scoring calculator

Scores combine as (I + C + E) / 3 or as I × C × E; ties share a rank, which is one plus the count of strictly higher scores. The best and worst rank per idea move any one score by one point, clamped to the scale, so a range of 1 to 1 means the rank is stable and a wide range means the ordering leans on a single guess. Mean and product reward different things: the mean forgives one weak factor, the product punishes it, and the engine says so when the two would crown different winners. It ranks the list you gave it; it does not weigh reach or cost, and it cannot tell you which idea is actually good.
