I forgot to include the message from Jiang that accompanied the latest slides:
The start time was 11: am, 4 May and end time was 11:30 am, 7 May, 2015, in Figure 6. The start was 0:30 am, 8 May, and ended by shutting power off at 11:00 am, 8 May, 2015 (Fig. 7a and 7b). Total run time was 96 hours. The excess heat (T2 exceeded 1300°C) was stimulated at 15:00 on 5 May, 2015, then the excess heat production lasted about 68 hours until power off, and self sustaining mode lasted about 15 minutes after power off (Fig. 7a and 7b).
