Here are my results: There's my evidence that there will not be a new speed portal.
 * If a speed portal slower than the slow speed portal was introduced, it would probably be very hard to jump over one spike.
 * If a speed portal faster than the very fast speed portal was introduced, it will be quite hard to control.
 * It would be anyway hard to code and test the portal.
 * The 4x speed portal would anyway be Way2fast.
