Thanks - it's always hard to know where these things will lead, and hopefully
there are a lot more interesting and educational discoveries to be made.

Looks like the big article I'd like to lay my hands on is

Lothar Haselberger
Scientific American
Vol. 253, No. 6 (December 1985), pp. 126-133 (10 pages)

It's on JSTOR is anyone has access.

I am sure there are indeed.

That's him indeed. Unfortunately, I do not have access. :-(

This is about the Pantheon in Rome, but it mentions Didyma.

Yes, hard to believe how hard some peoples work to impose some arbitrary 
meaning to some objects or proportions.

«Conclusions In Summary

Based on the best understanding we currently have of the object, and on 
the knowledge of normal fundamental limits of physics and laws of 
nature, we have to conclude:

     That this object was fabricated on a highly sophisticated 
subtractive manufacturing system, from a solid piece of granite.
     That the manufacturing system would require, at the very least, 
sophisticated mechanical technology and high-precision components.
     That the manufacturing system would necessarily have been guided by 
an automated control system, which could read the design as input, and 
produce the required motions as output.
     That a turing machine, of considerable sophistication, would most 
likely have been employed to create and operate on the design, and to 
finally transfer it to the manufacturing system.

There is no way, in which we can attribute the production of this 
artefact, to anyone who do not possess, at minimum, the level of 
technological sophistication and capabilities mentioned above. This 
raises some very interesting questions regarding the origin of the 
object, which we hope to be able to explore in future work.»

WHY does the author totally ignore that it could have been made entirely 
by hand WITHOUT any technology more advanced than Bronze age tools and 
lot of available time.
Once roughly carved, the object can get meticulously refined and 
smoothed by hand.

Because they never tried. Because they have no clue what can be achieved with
simple hand tools and time. Because they don't think about the amount of time
one had in those days. Time to observe, time to learn a skill, time to produce.

Amen.

I was going to answer exactly in this same vein indeed. That whole 
"sophisticated" mathematical description just doesn't prove... anything 
at all about the real technical skill of ancient sculptors.

Thank you sir! Just in time: I just broke my last vase remaining! :-)
