It looks that C&D changed this procedure back in '19:

I believe that it is not an apples to apples comparison with the older S2k timings.
The old way they did it, starting from 3mph, is 100% fine for cars with around the s2000 and twins acceleration times. I wouldn't be surprised is the 1ft rollout was a tiny bit slower than the 3mph starting point.

EDIT: In fact it is more beneficial to the s2000. They measured the BRZ at 1ft rollout as .3 seconds. That means they effectively started timing when the car was going ~2.27mph, whereas they would of started timing a bit later (with a lower overall time) if they timed it @ 3mph.

The example they used was the C8 Corvette, which gained .1 second in the new drag race method. The new system was to be more accurate in this upper level tier of super car performance.
