Marginally high CPC end to end readings

Sure this has come up before but yesterday testing after adding a spur and end to end readings on CPC come out about 0.2ohm over expected reading (was expecting about 1ohm from LL & NN (0.65)

Checked all sockets I could see (some were very old so suspect the sockets themselves might be a contributing factor) other possibility is JB under floor.

Question is would you just report this on meiw, start ripping up floorboards, recommend FI or what?

Earthing system was TT. Zs - 9.75ohms
Also there was quite a bit of original stranded copper in the circuit.

Thanks
