Well, his published results afaik lack a QQ-Plot using the packet 
delivery ratio PDR of RSSI vs. LQI. There may exist a cost function such 
that PDR = cost(RSSI) = cost'(LQI). Theoretically, RSSI and LQI must be 
strongly correlated in the absence interferers (both in system and out 
of system like microwave ovens). So I believe that there is such a 
function, and I would not be surprised if it is linear at least for the 
relevant interval. Excluding interferers is the difficult part here...
