Very good explanation. To add to this, you’re going to need to learn the trajectory and arcs of each person’s jump-ins, either through training mode or via live matches. In a short time, you should learn the difference between Ryu or Cody’s jump in distance and that of DeeJay’s, which can be quite ambiguous.
My advice is to go into training mode and have a dummy knock you down (throw, backthrow, sweep) and test different jump in scenarios on wake-up. Then replay the dummy and try to block the various different setups, paying more attention to where they are on the ground before they jump.
