| # 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. |
