Thanks so much for responding Bill - appreciated.
I guess I'm still a bit 'unfulfilled' - have been modeling the readout results of my recent actual races wagered and because spn showed up as the most valid variable of the lot - I then looked for it on the RDSS readouts.
I guess I am still wondering how (from where?) it shows up on the exported data if it is not included in original readouts? AND - there is definitely a significant difference in the comparison of SPN to BLBL rankings. Whatever is being used - it does not appear to be simply BLBL with a random "fake-out" number added.
Perhaps Ted will clarify.
Thanks much - Gary
