Wireless Wire Signal vs RSSI

Hi. I have two links using wAP60ad and the signal value is confusing to me.
Link 1 AP side:

[admin@AP_60ad] > /int w6 moni 0
       connected: yes
       frequency: 58320
  remote-address: 04:D6:AA:67:89:CA
             mcs: 8
        phy-rate: 2.3Gbps
          signal: 80
            rssi: -70
       tx-sector: 61
       rx-sector: 96

Link 1 STA side:

[admin@STA] > /int w6 moni 0
       connected: yes
       frequency: 58320
  remote-address: 04:D6:AA:6D:AE:65
             mcs: 8
        phy-rate: 2.3Gbps
          signal: 35
            rssi: -71
       tx-sector: 36
  tx-sector-info: left 3.8 degrees, up 3.8 degrees
       rx-sector: 96

As you can see RSSI is the same but signal is very different.

Link 2 AP side:

[admin@AP] > /int w6 moni 0
       connected: yes
       frequency: 58320
  remote-address: 04:D6:AA:A8:4B:2D
             mcs: 8
        phy-rate: 2.3Gbps
          signal: 80
            rssi: -63
       tx-sector: 37
  tx-sector-info: left 11.4 degrees, up 3.8 degrees
       rx-sector: 96

Link 2 STA side:

[admin@STA] > /int w6 moni 0
       connected: yes
       frequency: 58320
  remote-address: 04:D6:AA:C1:38:37
             mcs: 8
        phy-rate: 2.3Gbps
          signal: 65
            rssi: -66
       tx-sector: 31
  tx-sector-info: left 26.6 degrees, down 3.8 degrees
       rx-sector: 96

On this link after alignment I had 80 on AP side, 30 on STA side. Then when I got to testing it jumped to 80 on both sides and stayed that way. On both links I have 6.43rc17 as this one is most stable. Link 1 is 190m, link 2 is 645m. RSSI value and tx-sector is the same all the time, yet signal value can be different at times. Why?

Would like an answer to this myself, maybe also add some info regarding the MSC value that changes constantly without moving the link, I don’t see a lot of configuration options for this new tech.
