(OP)
I am working through a worked example of pg 436 of the 2nd Edition and I am a little lost with respect to the way this example locates the CoG of the pile group.  I am more familiar with doing this from one side or the other such as the toe or heel.

Has anyone noticed this or can anyone explain this to me?

RE: Peck Hanson Thornburn Fdn Engineering (2nd Ed)

If you're working from the center row of the piles, there's two (one plus two halves) on the left side three feet away and one on the right side three feet away. There are four piles total. The calculation is (2 x 3 - 3)/4 or .75 ft offset to the left.
Sorry if I'm just repeating the calc sheet.

Couldn't see the forest for the trees!  I checked it all ways to Sunday anyway and its all the same.
