if your doing the pendulum thing and under flying the kite , your going landing with a plonk, speeding up the kite wont necessarily help either.. in fact with poor take off it may make your landing worse because your going to stay longer in the air with more height and hence pendulum more

, looping as you come in to land effectively helps to bring the kite forward of your position so you don't pendulum in the landing.
also work on edging and pop as you send the kite , carve aggressively upwind just as you send the kite up, you should be able to transition real slow/lazy with sending the kite and land smoothly, so speeding everything up with the kite isn't such a factor in my humble opinion as your edge in board take off.
