Like any media comparison, they test the car on what tires it is delivered with from the factory. Being an old engineer, I take any track comparisons with a huge grain of salt when different tires are being used since that one single variable creates the largest possible variance in the tested outcome.
For example, in the upcoming track comparisons of the M2C and the M2 CS in the states (i.e. like C&D VIR grand course), does it make any sense to draw a conclusion about "how much faster" the CS is on PSC2 r-comp tires when the M2C was tested on a 10 year old street tire design? (i.e. Pilot Super Sport). It's kind of amazing to me that BMW is still fitting such an aged design tire when the PS4S has long been available which outperforms the PSS in every category, dry and wet, wear, comfort and noise...
I would much rather see the data from the cars on identical tires. In this case, take along an M2C with PSC2 r-comps mounted, and compare them. Given their past nature, if I were C&D I'd take along an M2C with RE71Rs mounted....just for fun!
