Yea those 90 for certain is still being held against you depending on exactly how old it is , but it doesn't drop after 4 years, and that 60 may still be affecting you as well. Honestly if I understand correctly and it's someone else's account you were added to as an au, just remove yourself as an AU and the account will come off your credit report. If your score rises considerably you'll know it was dragging you down and if it lowers significantly you can just be added back
