In general such an undertaking would be ... monumental. So the answer is no. At least not to our knowledge.
But limiting the comparison to *two specific models* might make the project possible.
We have no knowledge of the Randell Mill model, and little reason to acquire it. However, it sounds like you are familiar with it. If you are willing to do the initial work to begin making such a comparison (learn enough about our DRP to make an <u>intelligent</u> comparison with your RMM) and present it here we would almost certainly begin a dialog with you.
This actually sounds interesting. I strongly encourage you to put forth the effort.
Thanks,
LB
BTW if you have questions about specific aspects of DRP, needed to develop your comparison, please ask. We will do our best to point you to the relevant source material, most of which is here on this site.
