Hi TAB,
Can you please try again with the latest daily build?  We've added a face image
quality assesment (FIQA) to the "rebuild all training" option in maintenance
and when confirming a new face.  FIQA filters out blurry, noisy, and pixelated
faces from being used for training, which should help increase recognition
accuracy.

Cheers,
Mike
