I'm starting a blog article summarizing Graham's attempts to replicate the work of Ludescher et al. This should include details of how to download the necessary data, what R programs Graham used or wrote, known ways in which his work differs from that of Ludescher et al, and a side-by-side comparison of the graphs.
There's nothing here yet, so I'll say when there is.
