On the report is the earth fault loop impedance internal Zs or external Ze ?

If it was wanting Ze it would say "External Earth Fault Loop Impedance"On the report is the earth fault loop impedance internal Zs or external Ze ?
OK
I have run my test on the furthest socket
LN PSC 0.29ohm 900A
L PE PFC 0.91ohm 253A
All circuits are protected by a 30mA RCD main switch.
Thanks
Now for a lighting circuit I would usexpect calculated Zs = Ze + (R1+R2)
Ze = 0.17 ohm
R1+R2 = 0.25 ohms
Zs = 0.42 ohms
Is this correct ?
I have done the C&G 2392 test and Inspection fairly recently.
I am still feeling my way around and just wanted some reassurance.
This is a for an addition of sockets and light fitting.

Think I'll stay out of this.
The post wasn't a mistake I think you need a bit of guidance.Thanks !
Just not very confident, just didn't want to make a mistake.
Maybe posting was the first ?
