You are right, Ted. Actually I think the general concensus in the lab is that the pucks with the 7MM antenna will not work with the badges, which is what this test was checking. We’ll need to come up with a different solution for the badges, but we thought we’d make the pucks and the pagers for a solid version two for now, then move onto the chest-level badges. The vertical lines are nice, but they are sometimes in the wrong order, which is disconcerting

Though the comments indicate a good separation (by the CDF), when I look at the boxplots and try to imagine inverting them ( f(RSSI)=distance ), I still see significant areas of overlap between different distances. Or maybe because of the scale of the plot on the webpage, I can’t see so clearly the dividing line. It does appear that some high values for the 0.5m and 0.75m range overlap low values for the 0.25m range. I can’t tell exactly where 0.25m starts and ends looking at these.
