# We have one ADD32rr measurement, and two measurements for SQRTSSr.
# The ADD32rr measurement and one of the SQRTSSr measurements are identical,
# and thus will be be in the same cluster. But the second SQRTSSr measurement
# is different from the first SQRTSSr measurement, and thus it will be in it's
# own cluster. We do reclusterization, and thus since there is more than one
# measurement from SQRTSSr, and they are not in the same cluster, we move
# all two SQRTSSr measurements into their own cluster, and mark it as unstable.
# By default, we do not show such unstable clusters.
# If told to show, we *only* show such unstable clusters.
