oscar can only improve his stamina so much but he can never reach the stamina of pacman; it's his natural gift and if pacman comes in 100% condition it's like he has oceans of gas flowing in him. That's why he can wage full scale war to his opponent even if it's 1st round only because he feels he can keep it up. With oscar though, it may be a grave mistake to go to war immediately because he has the history of losing gas at later rounds against great fighters, his stamina reports [what he feels right now] may be a false sense of security but still, it's always good to hear that from him as a sign of confidence going to the fight..
