it seems to me that you have a misconception about sample sizes! the necessary sample size to arrive at a conclusion will vary from one investigation to another, as it is entirely relative. in the case of an ever-changing industry like esports where careers are short, 3-4 years is a significant period of time which is more than sufficient to reach a conclusion.
judging by how jingg was grouped in 2/3 of the champs he attended, we can safely arrive at the conclusion that he is a mediocre player who cannot perform when it matters.
in fact, based on his 2024 performance, it seems that he is nearing retirement so there is little more samples that can be gathered in the future.
on the other hand, derke has been grouped 0/4 times.
additionally, a quick glance at statistics shows that the player jingg CANNOT be seen in the top 10 of any global tournament, this is truly peculiar. I wonder why?
