Earth fault Loop Impedance Issue - Ze Value concern

[Sparkydelux]

Hi People

I have a bit of a situation.
I have 60A MCB incoming supply. Voltage at 210V [Fluctuating whenever it feels like].
Previous EFLI Reading I got was 17.3 Ohms
I then reported this to the client who in turn reported to Municipality who then took 3 weeks to 'resolve it'.
I went and did a reading today after the resolution and got 3.67 Ohms with a PFC of 110A
When I calculated the EFLI [Ze] I have got 3.666 Ohms. This doesnt leave much for the remainder of the Zs to operate.
This is the 3rd time I will be requesting a repair / correction, but I need to make sure Im not going to be proved wrong by saying that their side complies.
Surely there should be some tolerance or lower value to compensate the earth value on the consumers side.

If I was to fulfill the earth value on my side at my points, then basically every earth would be in 6mm to ensure its at the maximum value with least losses.

Thoughts and advice appreciated.

According to your calculations, what were the other values? About the earth, are they using the crows-foot arrangement and have they done a soil test?
