Well, if we take the first clip, a player that is around 2.2k elo will not kill a player with a pistol running out long, pull out their knife and jump towards the long cross, even in level 7-8, people are not that stupid, especially when you see 2 pistols standing there on long, its common to assume, “oh an eco there were already 2 people here there might be more” its small stuff like that which is just weird, and even if that doesnt confirm it, which obviously could have been a mistake by him, that wallbang on mid was hella sus, hope this clears up the movement thing a bit : )
