I see nothing particularly wrong with this ratio, unless the deadlift is a little light compared to the squat. It's quite common for the deadlift to be 50-70 pounds ahead of the squat at this point in your training advancement, if you have normal hands and proportions. Deadlifts are hard, and they are supposed to kick your ass. Make sure you've answered the First Three Questions, and that you're not doing something stupid like conditioning during your NLP. Post a video of both squats and deadlifts.
