Query: Kendall's Shape Statistics as a Classical Realization of Barbour-type
  Timeless Records Theory approach to Quantum Gravity   I previously showed that Kendall's work on shape geometry is in fact also the
geometrical description of Barbour's relational mechanics' reduced
configuration spaces (alias shape spaces). I now describe the extent to which
Kendall's subsequent statistical application to e.g. the `standing stones
problem' realizes further ideas along the lines of Barbour-type timeless
records theories, albeit just at the classical level.
