Doesn't really matter, it's not really scientific either.
For example: If someone decided anyone, lets use trump, was replaced and decided to push images and videos everyday on what they believe are "strange occurrences" and proof he is a robot, alien, reptilian, actor ect... regardless of the amount of videos or images, it doesn't change the probability that he is replaced since the reality is that he is not replaced
What then would all these images and videos evidence of then? It's evidence of that person's delusional ideation.
It is mathematical,, specifically statistical but the meaning behind the math is lacking.
As I stated it doesn't matter if you notice something odd every second for a year it doesn't change the probability of something outside of reality.
