Two months ago FCU jumped up by 30%, last month by about 20% and now it added another 10%. The growth is obviously slowing down as the next update is imminent.

Note: we don't have the data for the initial rollout of the first update to Windows 10 (1511, also known as Threshold 2). So it's a straight line from 0 to the first data point we have on August 22nd, 2016.
