Bluetooth signal strength and time the signal are seen are both continuums. So why choose fixed extremes in the first place? What's wrong with the sort of careful mathematical tuning we apply to other real-world models -- this problem isn't a million miles from cryptographic traffic analysis, where of course you incorporate other data (such as the person's recollection) and apply different parameters for analysis in one situation than another (such as on a train versus walking the street). Moreover, analysis need not be exact and need not happen only once. For example, if you've identified a "super spreader" then re-analyse the data and ask all contacts to be tested, whatever the signal strength or elapsed time acquired. I'm not defending the app, but if criticisms are going to set up strawmen, then they should not present their conclusions as applying to the real world. -glen -- Glen Turner _______________________________________________ Link mailing list [email protected] http://mailman.anu.edu.au/mailman/listinfo/link
