how do i hit it (not in tas)

dont press anything for the first 6 seconds of the level, once red ball hits the right edge of the first cart hold right, when the first and 2nd cart fully compress, hold jump along with holding right, let go of jump when you are about to land on the ridge between the 2 carts, and then hold it again when falling into the 2nd cart, keep holding right and jump for the rest of the level, and when you get the corner boost on the 2nd black platform, tap left for 2 frames (this has a 5 frame window)

Thank you
