In the results files we have: FP+FN+TP+TN != TotalNumberOfRecords. Why?

During the detection phase there is probationary period where no scoring is done. This probationary period is set at 750 points for data files larger than 5000 points or 15% of the total records for files shorter than 5000.

FP+FN+TP+TN = Total number of scored data points (excluding probationary period)
Total_Count = Total number of data points in the dataset (including probationary period)

Please refer to NAB Whitepaper, Section 3.1 for more details.
