It is no secret that I have concluded that the body of G1 is made up of far more sand and marl filled (or not)voids/magazines than most allow for.
It is no secret that G1's volume at 100 feet, comprises 80% of the final total.
It is no secret that elevating blocks to 100' is a lot easier than to 200' or more.
It is no secret that I believe the total number of Blocks to be closer to 1.5 million than 2.5.
Are you about to tell us that this void does not jibe with your speculations?
