No worries. DT-II was about finding limits for catapults and arrests. The catapult has no trouble for a max. weight launch for an F-35C - with or without burner I have no idea. However the burner is variable on the catapult much the same as the Super Hornet. It is some percentage below full burner during initial part of launch and at full burner by the end - all automatic - from 'pop' stall lessons learnt with the Super Hornet which is at 122% at JBD on burner then automatically at 150% by the end by design change. This was built in to the F-35C from the getgo. The amiable butler wrote about this some time back when F-35C was JBD testing but PDF no longer available at URL:
JBD Testing A Key Step For Joint Strike Fighter Aviation Week & Space Technology Jul 18, 2011 p.84

"...Even without the more extensive data provided by today’s sensor array, Super Hornet engineers gained valuable experience during JBD trials that led to a change in how the aircraft is launched. During testing, hot air was inadvertently recirculated into the air intake of the Super Hornet, prompting a “pop stall,” or hiccup in the airflow for the propulsion system. The result was a dangerous fireball coughing from the back of the Super Hornet, says Briggs.
The design fix was the creation of a limited afterburner setting for launch. Engineers crafted software such that the engine is at 122% of military power when a pilot sets it to afterburner. By the time the jet reaches the edge of the deck, the system automatically opens the throttle to full afterburner at 150% of power without intervention by the pilot, says Briggs.
Having completed the first phase of JBD trials with a single F-35C, engineers are eager to test a more realistic scenario with one aircraft in front of the deflector and one behind.
Because of this lesson, the limited afterburner setting was designed into the F-35 in its infancy...."
