Good try, but your guide is quite off. Godswords shouldn't be used to train with under any conditions, and Saradomin sword is much better. As for attack with defender, Whip is clearly the best. Your formula may be right or it might not, but the best way to train isn't depending on bonuses, but rather the weapon's speed and it's efficiency. If this was your own personal opinions on the best weapons, I would let you think what you like - but the message you seem to be trying to convey is "these are absolutely the right weapons to use".
