Ro200 cam and CR

[pokemon]

Hi,

I'm looking for data about the Ro200 wide lobe camshaft fitted in my 68 912. Is there someone who knows the opening and closing points of inlet and exhaust valve for this cam and the "standard" 912 cam?
Reason? During previous enginework i calculated the CR based on the cylinder volume with the piston at bottom death center. (static compression ratio). The CR was so set to 8.7 for long engine life and lower octane fuels at the pump.
This now seems to be the wrong way to go i read in one book. Actual CR should be calculated based on the cylinder volume from the point the inlet valve CLOSES (dynamic compression ratio).
The engine (1600cc)now lacks torque and i think because i should have taken the dynamic compression.
If i can get the data of the Ro200 cam i can see how far the CR is off.
Is there someone with a 912 engine with a CR based on the dynamic compression ratio with good results who can confirm this is the good method?
The maestro in his books uses the static compression... How about that?
