User blog comment:Martialmaniac/Gon's "Round 2": A Hatsu ability?/@comment-32818639-20180525224830/@comment-5780397-20180525231234

Iìll specify just because I'm not sure I understand, but Round 2 seems to allow Gon to charge twice as much aura as a regular Jajanken attack, so in that sense it's not only about skipping one chant. But yes, if you read what Knuckle says in chapter 211, it does seem as though he must decide to use Round 2 beforehand, he considered Paper and Rock the same attack.
