Last night's results did not "give a good working compromise between real and false detections." There were several very plausible but false decodes. These appeared much more frequently than they do on OPDS which in any case gives enough additional information on signal quality to be able to spot most false decodes. It's a nice idea, but the real/false threshold is set much too far towards 'real', making the resultant information next to useless. And what is the "200%" fade figure all about? I am 1000% sure I don't know.
