using regression to get existing surface

I am currently working sac for road way and i want to use the api function that do some regression in order to do fill benching depending on the existing surface's average slope. The condition is if the EG slope is grater than 20% the sac will do the fill bench and if its less the sac will do daylight. so may question is how can i do the reg using more than 3 or 4 points.

The surface links collects elevation data at all the tin lines it crosses...The regression method is to be used in tandem with a surface link's sampling of the surface data... Therefore your regression analysis will be directly reflective of your surface resolution and length of your surface link.

so what u are saying is if i use one  surface link (auxiliary) the reg will calculate the slope of that surface by creating links between tin crossing points?

It will return the regression slope through the link's points.
