I don't think you're realizing the graphs aren't on a common scale, look closer at the vertical axis' labels. The peaks of each threshold are vastly different.
I'm not an idiot, you know.
Appearing to have a minimum of 30 active people at any given point in a day and appearing to have a minimum of 100 active people at any given point is not "relative", it's a very direct lesson in perspective. The maximum active of a 10 minute threshold never even reaches the minimum active of a 30 minute threshold.
If you're going to be this way about it, here's a very direct lesson in English.
rel·a·tive
/ˈrelətiv/
adjective
considered in relation or in proportion to something else.
Given any point in the day, on any of your graphs, any other point's distance from the first point has the same proportion (or, is relativistically the same distance) when compared against the rest of the points on all graphs, barring noise. That's what makes the graphs look extremely similar.
So, yes, it is relative.
I'm not trying to argue that the numbers aren't or don't feel fudged. I'm just pointing out that Osay isn't innaccurate in his statement.
