Hello Community

I've some questions about the TPCv2 Plan Quality Index in below output

Leader Automatic Transmit Power Assignment
  Transmit Power Assignment Mode................. AUTO
  Transmit Power Update Interval................. 600 seconds
  Transmit Power Threshold....................... -70 dBm
  Transmit Power Neighbor Count.................. 3 APs
  Min Transmit Power............................. 10 dBm
  Max Transmit Power............................. 30 dBm
  Update Contribution
    Noise........................................ Enable
    Interference................................. Enable
    Load......................................... Disable
    Device Aware................................. Disable
  Transmit Power Assignment Leader............... HP-AMM-WLC01 (10.1.59.1) (::)
  Last Run....................................... 479 seconds ago
  Last Run Time.................................. 9 seconds
  TPC Mode....................................... Version 2 Per-Channel YES
  TPCv2 Target RSSI.............................. -67 dBm
  TPCv2 VoWLAN Guide RSSI........................ -67.0 dBm
  TPCv2 SOP...................................... -85.0 dBm
  TPCv2 Default Client Ant Gain..................   0.0 dBi
  TPCv2 Path Loss Decay Factor...................   3.6
  TPCv2 Search Intensity......................... 10 Iterations
  TPCv2 Plan Quality Index....................... Overall 546.1 Coverage 623.2 CCI   0.6 Ratio   0.1
  TPCv2 Target Plan.............................. To be reached in 1 TPC runs

Q1:  For the Overall value 546.1, What does it mean? Which indication I should understand reading such value (good, bad … etc)?  What is the range that WLC use to assign to the parameter? Is between 0 and 1000 for example? Which is better close to zero or the other way?

Q2: • Coverage 623.2, What does it mean? Which indication I should understand reading such value (decent coverage, not good … etc)?  What is the range that WLC use to assign to the parameter? Is between 0 and 1000 for example? Which is better close to zero or the other way?

Q3: For the Ratio, What does it mean? Which indication I should understand reading such value? between 0.0 and 10.0 for example?  Which is better close to zero or the other way?

I'm asking because, I collected the Run-Config before performing the Site-Survey and I want to compare them with the values after the site-survey, but couldn't find any documentation and recommended value ranges in this ..

Regards
