Since we started the 100 circles study four months ago, the number of connected profiles has grown by more than one million. I have compared for the original "Focus profile" Jean-Joseph Vatant, the population of circles before and after this extra million. The image below is showing the growth of circles 1 to 40 (click to enlarge).
The growth of the very first circles is not visible at this scale, and relatively very small (putting my steady stubborn work on them in perspective, just in case I'd think I'd achieved a lot). The growth of circles 1 to 20 is roughly one thousand profiles, that is one thousandth of the total growth.
At first sight the circles with the largest growth are roughly the ones which were already the most populated (around distance 30), but looking more closely, it appears that the greatest growth happens just a bit closer than the most populated circle.
The most populated circle was in November and is still in February the 30th, but the maximal growth has taken place in the 28th and 29th circles.
Meanwhile the mean distance to/from Jean-Joseph has "dropped" a little, from 33.15 to 33.01, still waiting for the magic shortcut which would make it drop drastically.
In interpreting such figures, I would not want to get carried away. The growth of circles is due both to addition of new profiles, and reconnections bringing back profiles from further circles. The part of each cause is difficult to assess, but what is observed for the 28th and 29th circles has probably something to do with reconnections.
Similar work for other Focus profiles is under way, and we'll of course continue to monitor those figures over time, and post updates as seen fit.
