The L/L Meditation Pyramid

Not to challenge, but rather to offer a mild but perhaps nerdy perspective:

My take on the accuracy issue might have actually referred to the inherent geometric challenges, such as:

Alignments of sticks or tubes within a "stick-frame" introduce some degree of variance from original stone surface alignments, regarding edges, surfaces, vertices or corners. Solid stone structures vary from purely stick frame geometry. Nevertheless, the effect of human intention can, to a useful degree, transcribe the effects sought after. Obtaining wanted effects can be more important than study of precision geometry.

So natural questions could conceivably arise. Should alignments pass through the centroids of the sticks or along the outermost edge of a frame? Could the cross section or 'straightness' of a stick or tube introduce slight-variance from strict geometric standards? How should the corner joints be fitted? How should corners be fastened? Does the fastener add to the variance factors? Are base components helpful? What if the lawn is slightly sloped or if the grass is clumped slightly higher at one corner? What if the base is slightly out of square?
