I think that what may be of interest to the OP, is that once you have analysed all the objective specifications, there also remains some “unquantifiable” subjective variation in how each end user experiences and interacts with their particular camera and how their system behaves in real life versus expected behaviour on paper.

In Allan’s case, as with many others, they appear to have successfully mastered either side-by-side, piggy back or off-axis guiding which makes the (2nd) guide chip of the SBIG dual chip cameras redundant. Alas, in my case, despite my best efforts, I haven’t been able to eliminate differential flexure so I am “doomed” to co-exist with the SBIG dual chip cameras.
