Im pretty sure I have a legit squat just because i go 95 doesnt mean its not a good squat, In reality going to 90 or past is really bad for you knees manly your patella, patella tendon (top and bottom) and it can be pretty bad on you meniscus. Thats just when you do it 100% correct, most people dont keep every thing perfectly inline and leading to damage to you ligaments and tracking of you patella. All in all ill stick to my just before 90 and be able to move when im 50+ rather than go to 90 just to say I go to 90 and never walk right again.
