When hitting either side ramp, Press Up + B for the Frontward 50/50 and slide on the rail for a short distance. Before you are ready to go back down, hit a few short moves and your skater will automatically jump in the air from the rail to the height you were supposed to reach if you did not hit the 50/50. The best you can do with this process is to do the 50/50, then a few short moves, and end with the Noserock. It is possible to pull off six moves by doing the 50/50, some Shove-it 360s and then ending with the Noserock. This is helpful in X-Rage mode when trying to max out the stats of each skater.
