Go into level 1. Anywhere on this pixel works on >99% of it. (More than 99% of subpixels work) This setup is more consistent than the previous one by krackerz, in which only ~66% of subpixels work. The setup is 2 pixels passed the dark outline, then it is a frame perfect jump that you just hold on, with a 1 frame long crouch at the third frame of the jump.
