Captain Falcon (SSBU)/Neutral attack/Hit 2
The second hit of Captain Falcon's jab comes after the first hit. Additionally, this move can transition to the infinite jab if the button is pressed between frames 7 through 9. Otherwise it will initiate the third hit (known as the Gentleman). The move deals 1.5% if connected.
For rapid jab, you can input it on frames 7 through 9 and it'll start a frame later. That frame range is what is listed.
