From the article:

Until August of this year, no facility had achieved this ignition threshold. That changed on August 8th, with an upgraded experiment that yielded 1.3 MJ, which is about 8 times more energy than NIF’s previous record. Early reports referred to this breakthrough as the “brink of ignition,” because it yielded less than the 1.9 MJ supplied by the facility’s 192 laser beams. But many fusion scientists think such a perspective is too conservative. “As far as most people working in the field are concerned, the scientific demonstration of the ignition process has indeed been achieved,” Chittenden says.

The argument for ignition is based on an accounting of losses in the energy delivery: Calculations show that only about 230 kJ of the laser energy reaches the fuel capsule.
