Yeah... I'm not entirely sure what to make of this. Congratulations?
Also, squats largely hit the same muscles as deadlifts, and they are sorta kinda assistance exercises for one another lol, so yeah.. it's certainly possible.
Also, classic westside, IIRC doesn't deadlift so much as they squat, and they're pretty decent at deadlifting too, so you certainly don't need to deadlift err day to improve it.
