Not just a grain of salt, a *whole truck load of salt*. It's not even the 1% accuracy of their measurements that's the real problem. The real problem is that they never demonstrated that positrons are in any way related to "dark matter". They simply *assumed* that high energy positrons are related to DM, and then they pulled another obvious affirming the consequent fallacy out of their back pocket.
The fact of the matter is that positron emissions *are directly empirically linked* to electrical discharges, not "dark matter". Their aversion to EM field activity in space makes their entire belief system predicated upon pure denial. They never even *mentioned* the "most common" source of positrons in that article, not even once. Even their claim about "pulsars" being a source of high energy positrons is due to the fact that a heavily magnetized spinning object would necessarily induce currents in the plasma around that object, and produce (drum roll please...) "electrical discharges" in the atmosphere around the pulsar. They intentionally avoided all use of the term 'discharge' however.
Like I said, their entire belief system is predicated of *denial* of the relevance/validity of EU/PC theory, and it's predicated on a series of affirming the consequent fallacies.
