The only problem with this is the stats for "lives saved" are based on subjective impressions of those who used weapons themselves one way or another or said they did. It's like asking people "if they drive safely" (and without even finding out first from other sources if they even drive to begin with).
What independent investigators found would be necessary to throw in the mix - including if the event exists on record.
The stats for other categories are from independent resources it sounds like. So, the "clock" is comparing objective facts about some events with subjective assumptions about another. And according to the actual tables of the researcher only 64% are even on record as happening to begin with - and of these an undisclosed number are self-reports only.
What you'd have to start with are actual situations that are on record as having occurred - as authenticated by independent resources. And this means they are on record from more than just a self-report by the one "victim". And then you'd have to compare what the "victim" said about them with the official conclusions. None of that is here.
It's primarily subjective perceptions that are being studied - and compared to verifiable events.
Very unreliable "study" as it is described.
