API Rank_Perf - Provide Access to the "Log"

When running a Ranking System Performance analysis on the main P123 website it is possible to click the “Save Log” button and gain access to a detailed summary of the rank performance run. I would like this same log to be available through the API. Ideally the log could be returned in some kind of structured fashion (like a json), as opposed to just a character string that would have to be parsed.
