Kia ora @Naga. No worries for the delay. My hope was that, as this was part of your thesis, then some outside assistance with Quality Assurance might be of assistance in progressing the thesis as well. I recognise that the system cannot in reality be a part of the actual research, it is a means to an end. However, I was concerned as much for the accuracy of your calculations as for the benefit to my students.
Thanks for the rapid response. I felt the need to re-look because I was hoping that the odd result would not have invalidated work already done, or caused a deep dive that was indicative of a thesis issue.
Look forward to you finding the time.
