In Cogo / Point Average, this option introduces a distinct averaging method for GPS measurements that applies a Chi Square analysis to the identical points, as read from the raw file, and includes blunder detection and blunder point removal. 

Points collected individually within Store Points, or by A for average within Store Points, sharing the same point ID, will be averaged by statistical methods including estimates of accuracy, which under most conditions of measurement will exceed normal RTK accuracy. This option can be viewed as a form of post-processing in the field, leading to greater accuracies.
