You are missing the point entirely,
Gwendoline Christie almost certainly can't bench that person (i'll humour the absurd "who can bench more" frat bro thing for the discussion). If Gwendoline Christie was male, she would be 3 standard deviations larger than the average. Her testosterone levels are "nerfed" due to being female.
Gina, and any female bodybuilder for that matter, are of course stronger than your average man, but they are again, "nerfed" by biology, if they had the testosterone production of a man due to being male, they would be considerably stronger, maintain better muscle mass relative to the hours they have put in bodybuilding.
In the in game implementation, a high strength female charcter would be an impressive rarity, demonstrating great strength, despite biological hinderances. This correctly acknowledges their uniqueness, and brings their other traits to the table (considerably higher in int or "smarter" than other strong characters)
