# 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.
