Thanks Tony - are the 3-leg distances of your stand the same as the original support's?
As your table doesn't seem to be supported neither at its Bessel nor the Airy points,
I wonder about how these dimensions came about.

As soon as you put some heavy loads on such a table the idea of leg positioning for minimum sag or slopes etc. in the unloaded condition become somewhat irrelevant. In optics work you will generally be placing light weight objects with minimal effect on table stability and great accuracy is paramount. For my use there were other considerations, one being the maximum sensible area between the legs for a storage shelf.
Engineering is about what works and this works.
