Reliability of Switch (Juniper) TDR Tests

I just finished troubleshooting a few new runs that were installed. I ended up running the TDR test on all the switchports. How reliable is the info, or is there a better way to interpret the results? I'm not seeing any performance issues on the ports that are up and have faults.
