The numbers on Easton (and all the other aluminum arrows I have
encountered) are understood as -
Given an arrow size (2314), 23 - 14
23/64th outside diameter
.014 wall thickness
All dimensions in inches
any alernative points of view out there?

These numbers apply only to Aluminium tube shafts, and the convention
is often used by other Al arrow manufacturers.
The first 2 digits give the external shaft diameter in 64ths of an inch
The second 2 digits give the tube wall thickness in thousandths of an inch
e.g. 2314 is 23/64" external diameter, 14 thou wall thickness
The greater the diameter or the thicker the wall, the greater the stiffness
of the shaft. A VERY approximate rule of thumb is that if you go up in
diameter by 1, go down in wall thickness by 1 to preserve the same stiffness,
e.g. an 1814 shoots a bit like a 1913 or a 2012. Don't rely on this though, use
the Easton chart!
Some carbon shafts are labelled with a number indicating the Al shaft diameter
with an equivalent stiffness, e.g. a Beman DIVA 19 shoots a bit like a 1914/1916
Al shaft. If the number is in the hundreds, like on an ACE (e.g. 670), this is the
spine of the shaft determined by a standard method (see the Easton brochure). The
greater the number, the lower the stiffness, e.g. 670 is stiffer than 1400.

The first two digits ar the outside diameter of the shaft in 64th of an
inch, i.e., 2314 = 23/64ths of an inch O.D.
The last two digits are the wall thickness in thousandth of an inch,
i.e., 2314 = .14 inch wall thickness

Surely that should be 0.014 inch wall thickness (14 thou not 14
hundredth). I know probably just a typo but we might as well get it
right.
