Score dimensions
weights sum to 86
The published score is five dimensions, each weighted for the category. "Published criteria" is the criteria block above; the other four are the engine's own terms — availability, friction, trust record, measured data. Each bar is one side's points out of that dimension's maximum; the weight beside the name is its points of the 86-point weighted total. The published criteria above can fill 24 of the block’s 30. A weight marked “constant here” belongs to a dimension every ranked product in the category holds at the same value: it still counts in the total, and it orders nothing here.
