Original number of links off stafloor calculated from known weights of components. 

 Based on 3% by weight absorption to saturate the concrete. 

 New chain count based on retrieved sphere data. 



Extra shackle found on retrieved chain which changed number of links from Reference 1. 

 *^Actual quantity of permeated water was 1.24 ft^.
