How to get really high at dolphin Olympics 2

Start by jumping out of the water and entering smoothly to get a "nice entry". Next continue moving right, but more horizontally than vertically. Keep hopping in and out of the water to gain speed. Try to set limits at the moon so you can keep moving right and getting faster. With about 10-20 seconds left, jump more vertical (but not too much) and hold the corkscrew button (down). You will hit a starslide because you are holding grind. As soon as you hit it, pop off by hitting up. Hold down again and repeat. The last starslide ends about neptune/uranus so try to have enough speen to reach "the end of the universe". Keep in mind on starslides, the faster you are going horizontally, the higher you travel when you hit up.
