So, a 30% increase in weight vs, only a 10% increase in power. Plus the added benefits of all the HiPo suspension gearing and drive train of the Z06 makes for a fair comparison?
And the Z06 is A LS7 normally aspirated motor
While the CTS V is a LSA supercharged motor, Yes they are both Gen 4 motors, but that's about where the similarities end.
So, really when you lay it all out if they can get the numbers you predict then I certainly won't complain. All I'm saying is for what the CTSV is, to even be as close as it is to the Z06 is incredible.

Well if you don't think that is fair then even comparing it to a regular LS3 with 430 HP. Both are 6.2's one is supercharged to make 120 more HP.
Yet the LS3 has run 11.7 showroom stock.
Now the coupe is about 3300 lbs which makes it 7.67 lbs per HP
The CTS V is 4300 lbs which makes it 7.73 lbs per HP
Basically identical from that aspect. Yet it shouldn't be almost 8 tenths slower. Compare what you will, these engines don't have that much not in common. There are may similarities between the LSX engines
