Etap grounding model

[HamidEle]

I am creating an ETAP grousing model. Received the soil resistivity data with at different depths with different probe spacing. Wonder which numbers should be chosen for two soil layers. Appreciate it for any inputs.

See : IEEE 81/1983 IEEE GUIDE FOR MEASURING EARTH RESISTIVITY, GROUND IMPEDANCE,
Annex B Determination of an Earth Model
The earth model is limited to a two-layer soil configuration.
