# Node Model Score

For Blue Locate and Blue Read, a node model score (model match score) is a combination of two things:

- The average score of the features in this model

- The "geometry score" based on the geometrical arrangement of the features in this model

As the geometrical arrangement is included in the calculation of the overall model match score, the node model score could be less than 100% even when all the features have a perfect score of 100%, given that the geometry score is less than 100%.

The "geometry score" is simply a measure of how much the relative positions of the features differ from the relative positions of the nodes in the model. For example, with a node model with 3 nodes, given each feature of score 100%, the overall model match score will be slightly less than 100% because its geometry score will be less than 100% unless the spatial layout of the features exactly matches that of the model.
