Calamity Anne vs Superman

How long would Calamity Anne last against the Man of Steel in a sparring match before her powers run out?

I feel like for my Amphibia/DC crossover AU fanfic I wanna write after Superman and the Justice League get to know Anne and learn about her powers and Andrias, Superman takes Anne to a empty spot maybe Nevada at the Grand Canyon and asks her for a sparring match to test her to see if she is able to control her powers

I feel like with how fast Anne is in calamity form she could most likely keep up with Clark and maybe even hurt him slightly

Idk if I should nerf Superman a bit but I want Anne to fight him as a sort of an equal.
