After some research I have found the answer. Just as I expected actual takeoff distance to 35feet screen height would not have allowed safe stopping distance in case aboart was initiated at decision speed/rotation speed. What Cessna has done is to combine three different computations:


accelerate-stop distance
accelerate go with single engine to 35ft distance
and two engine takeoff distance multiplied by 115%


Longest distance of the three of those cases was given as takeoff distance.

Unfortunatly Cessna does not explain that by takeoff distance tables assuming correctly that most will follow blindly never considering that actual takeoff distance would never allow to stop in case of V1/Vr cut.

Hope someone will find this usefull !
