another old one I think myself and others have known since the projectile/super freeze "bug". can get a taunt and punish off, or a full jump in, not sure if both; height, angle, as well as EX kunai and probably other factors can play an effect, along with what button strength Shoryuken is used. The window for hitting the projectile as the super freeze happens, to cause free movement, is small, but apart from that, the Shoryus can trade with, lose to, or beat kunai/kusami suzaku
