Experimenting with stack charts wifi speed "bins" instead of percentiles. This removes the distraction of comparing "how great" the great wifi connections are, so you can focus more easily on how bad the bad connections are. "Green" is essentially "fast enough to stream Netflix at full rate." Still getting some odd results even at pretty high signal levels, though they may be bugs in the test rather than in the wifi.
