Momentum?
Higher approach speed?
2 engines at idle produce more thrust than 1 engine at idle.
Different view over the nose may lead you to perceive that you are further from the touch down zone in the 310 than at the same distance in the 172. Hence you may be cutting power in the 310 closer to the spot than you think.
Be aware that the 310 wings are closer to the ground so ground effect / cushion could lead to a longer float.
Different winds will lead to different ground speeds.
All these are little things but they add up.
You will soon learn where the “right spot” is. You won’t need or have time to think about each various factor. “Practice makes perfect.”
Remember learning to ride a bike? Terribly difficult but a week later you could not recall what all the fuss was about..after all it is so easy.
Enjoy the 310.
