 "symptom": "Four runs at the same PHY rate and the same MEAN drain rate, differing only in the time shape of the drain, gave survival times spanning 1.84 times: 25.6 seconds steady, down to 13.9 seconds with a 2-second-half-period square wave. The bursty case delivered 30,659 B/s against the steady case's 29,700 \u2014 3.2% MORE data \u2014 and died in 54% of the time.",
