Looks like it grabbed a page from a soil mechanics textbook for you. There's more to it, but the general concept is there. How much information do you have from the actual lab test on the soil?

We have no info. Although we've done investigations during other projects in the area and we know the bedrock is typically slate, and the UCS would be 25 worst case scenario. Using that relationship I found the shear strength is roughly 14 Mpa.

Shear strength is half of your UCS

To be clear, are you estimating the strength of rock or soil?
