The scheme described above is only to the purpose of dealing with the question placed.
Structurally any pyramid shape made of discrete blocks of stone is likely to generate some arch action by itself. This arch action then will have some horizontal stresses at the central vertical axis be compression, hence denying the general scheme above, i.e. the scheme above is likely under the levels in which the compression generated by the arch action are overcome. The arch action shows however the edge of the square spreading, and this tension is akin to that described in my above entry, trying to generate a vertical hole at the central vertical axis, and to which any built-in crack (room) would be sensitive.
