0.4s faster compared to the new M5 non CP, in a bit colder conditions and on the same tyre (

I think that is fairly even. I was expecting a 1 sec difference on Sachensenring. Maybe the difference between non CP and CP is more in terms of feel than outright performance. M5 CP was 2s faster from 200 to 300, which is nice, but other results are pretty even too.
