And that has Prof Stolper and the rest of the rover science team leaning (with a lot of caveats) towards a classification that sits on a well-established sequence of alkaline igneous rocks - one that goes by the name "mugearite".
His time trialling needs room for improvement to push for a podium place, as does that of team-mate Juan Miguel Mercado, the other major hope in the general classification, who has so far failed to live up to his early promise.
The team also applied their method to the Pentateuch, and were able to verify the general scholarly classification of those books into Priestly and non-Priestly sources with over 90% agreement with the current scholarly consensus.
