CS 8.2-8.6
BM3 CS 8.0-8.3
BM3 STG1 6.8-7.0
I am susprised with the numbers posted above for the CP. Doing a survery of different European magazine I came up with the following average results:

To remove the effect of the added grip at launch provided by PSC2 when the cars are so fitted, I only set out to capture the 100 to 200km/h acceleration. I compiled 21 different tests and then averaged the results for each M4 variant (DCT only). While this is not the most scientific approach, it does provide a decent perspective. Here are the results:

100km/h - 200km/h acceleration
9.52 M4 Base (6 samples)
.... ∆ 0.20
9.32 M4 CP (9 samples)
.... ∆ 0.67
8.65 M4 CS (4 samples)
.... ∆ 0.20
8.45 M4 GTS (2 samples)

First, I think this dispels the rumours that the CP is not any quicker than the base model, having a ~0.2 second advantage from 100 to 200km/h. Second, it also shows how the CS pulls quite strongly in the top end, being ~0.7 seconds faster than the CP and only ~0.2 seconds short of the mighty water injected GTS. Which is in line with the conclusion reached in the OP when looking at the power charts .
Further, according to your dynos, the CS would not be much faster than a CP on a 100-200km/h as it makes almost the same aversge power in the power band, which is inconsistent with the above results.
