Also, I still adhere to the fact that she probably uses her quirk more than you'd think. Such as observing Iida's motors for when and where he's going to accelerate. She can see up to 5km away, at that range, she could probably notice the most minute changes in his motors.
And well, being an engineer, she probably could figure out how exactly his exhaust ports work.
