You aren't exactly wrong and she is seen as a superhuman by japanese standards of her time but that's on her rather than the nippon yumi bows made with mystic bamboos. It isn't wrong that she'd be able to draw that fantasy bow specially since her father likely made her train using the hardest one he could find, the weird part is the yumi bow having the greatest draw weight in the world.
It's the same as saying katanas being the best swords possible that can cut steel.
Makes me wonder if the author will later do the same to samurai armor and their helmets.
