THE WITNESS: Well, it just looks at the resisting versus the pushing load. The failure load. It just looks at the two to see if they're balanced or not. THE PUBLIC: Right. So these models were done without construction. Construction adds weight, adds vibration to the top of the slope that's presently being right on that line. How does that affect the chance of it moving down hill faster or quicker? THE WITNESS: Well, no, that's not necessarily true. There's a -- just trying to read it so I read it properly. So when you're looking at the diagram it's D. So it's basically -- it's a factor of like how much construction is impacting the site. Langan did assume that there will be, you know, somewhat construction impacted, as well as we also assumed the same. So if you use a number one in the model it assumed that there's a disturbance going on. My big disagreement was with the GSI, which is something that it -- actually the two together actually sort of magnify each other. So if you're using a high GSI it artificially lowers the potential factors of safe, or
