that is some hairy riding and big boosting no doubt.
But to think about estimating height, also think about angles.
Camera lens effect often makes jumps look bigger -wide angle lens exaggerates the height, and telephoto lens flattens the picture hiding the fact that the rider is often approaching at an angle, not moving parallel as it can appear.
For example IF this guy was approaching shore at 45 angle, and accelerates to 40kmh during the boost, he WOULD have travelled 39m and be 28m closer to shore at the apex than at takeoff. If the speed was only 30kmh, he would still apex 21m closer to shore....

Being closer or coming closer makes it looks way higher, to the brain and also to the camera.
Not that it isn't an awesome high jump.
But the geometry needs to go into 3d, and consider time and camera lens as well, to estimate height.
