They counted stuff, the numbers they counted are in the report, the numbers matter, and an idiot like dreamy could have counted the same stuff without any problems. What is this neurotic obsession you have with the source and analysing sources? Just analyse the fucking information, it's simple.
(1) When you count the number of unsolicited mail in ballots sent, the result is the number of unsolicited mail in ballots sent.
(2) When you count the number of heart inflammation cases after vaccination, the result is the number of heart inflammation cases after vaccination.
These things, (1) and (2), are how counting works.
(3) The proportion of heart inflammation cases that were counted is equal to the probability of you suffering heart inflammation after vaccination.
This thing is not about counting, it is an equation relating two different things, which is science, and the only way to know whether or not your equation is correct is to use the scientific method (predict some consequence of the equation, then check it by experiment, or if you can't do that then you need to break down and investigate all the component parts of the equation, check as many of them as you can, and then hope the sum of the parts is correct). You don't know how to do this, nor do you know the difference between counting and science it seems. What you do know is that the equation in (3) is almost always going to be wrong, for reasons you are perfectly capable of figuring out should you care to think about it. Alas you don't think enough, you're too preoccupied with your virtue signalling equivalent of following the science.
