Great post @paulag. I think adding a column for author REP of the top 50+ posters by post reward lost due to flagging would be a very useful thing to give this more context. Obviously the very act of getting flagged and losing rewards lowers your REP - but I think you could still learn something useful from this, particulary where the author flagged still has a decent (or even exceptionally high as in the case of @jerrybanfield) REP. Whatever you think of @berniesanders squabble with @jerrybanfield, looking at Jerry's current REP of 73 and current pending past week author rewards of $4,558 USD leads one to believe that he will probably be able to weather this storm - it provides valuable context.
Of course if you can somehow figure out the impact on author REP from the downvote and factor that in to the analysis - e.g. current REP and what REP would have been without the downvote - that would be even more informative.
Keep up the great work :) Much love - Carl
