When will the Quarantine of Earth be lifted ?

[Tenet Nosce]

Another way to look at it... as we (theoretically) move from 0.1% to 2.3% accessing 4D vibrations, that is roughly 150 million more people using 4D catalyst within a relatively short time frame.

Is that like 2 and 3 standard deviations from the mean (which I'm assuming is 4th subdensity)?

Yes- although in this particular graph the mean is on the border between 4th and 5th subdensity. It's debatable if that's actually the case, but I think a fair approximation.
