Well actually I don't think
Well actually I don't think you properly did your research, both C&D and R&T posted identical or better times with the 2015s, Motortrend somehow managed to have a slower time, although that could also be because their car as stated in the article has literally every weight changing option except the lighter Recaro seats. Whether they chose those themselves or its just what they received from Ford is an important question as is whether they tested the cars under identical situations. But C&D posted faster times then their long term 2013 Track Pack GT or their 2011 Brembo Pack GT. R&T to my knowledge hasn't tested a GT since 2011 and of course it was a Brembo Pack one and yet again the 2015 times were slightly better. So you shouldn't really be too disappointed that one publication recorded a slower time, also the 2015 will definitely be much faster in the corners. Idk what ppl are truly expecting, did anyone really think that this car was all of a sudden going to be as fast as Vette or similar sports car, that's ludicrous! This car is still plenty fast, not even mentioning that as always Stangs are easily and cheaply modded to go much faster then stock and even beat out high priced sports cars of similar or even more power.
