I can see why RogueT's chart stops at around 1975 when looking at the record to the present day as provided here on skepticalscience.com. What I can't make out is where rogueT's data could have come from. It's nothing like the records from the different reputable sources. It could just as well be a child's kindergarten scribble that someone put labels on. And given RogueT doesn't provide a source I reckon that's as good a guess as any.
