Your first graph refers to the DB 601A, with some 100 hp less IIRC. Speed at s.l. matches the C-7 in-game, but the latter has a DB601N rated at 1200 hp. The second graph is just an estimate based on the "drag and power". It gives only 3-4 km/h more to the C-7 against the C-1/2 for 9% more power ... just 1% more speed ... not a great interpolation imho ...
