The abstract and summary headline the −0.09 "average" own-price elasticity for IS-B (real-time) power, which is the mean of the six coded IS-B period elasticities; the LOS-A/LOS-B rows are background firm-rate results, not headlined. || "Using data for large industrial users in 1986, the estimated own-price elasticity response averaged -0.09, implying a small but significant reaction to the changing hourly prices." (p. 99, printed; also p. 114: "The \"average\" own-price elasticity of demand for power from the IS-B rate was -0.09.")
