Nice job! Your squat is super deep like your almost bottoming out and losing tension in your hamstrings. Bench had another 5-10lbs in it. DL form looks good and no idea why it's not higher. My deadlift moves better training only 1 day a week with 1 heavy set and 1 backoff set but everyone responds differently at this stage. You'd most likely hit a higher DL testing on another day.
