Position at the end of the runway (or up to 4 pixels away) at the top-right of the room, gain run speed, perform a last-frame jump and ceiling mockball, then equip or unequip Spring Ball in order to reset Samus' vertical speed and just barely make it onto the ledge with the item.

Clears obstacles: A

Dev note: Goes to 3 because opening the gate mostly only makes sense when going back to the right for a longer runway or obtaining the item. FIXME: Variants with shinesparking or Geruta damage boost can be added. (Energy from immobile, CF, or energy free sparks)
