I was contemplating on why one tire I repaired for Mimi leaked and now I have found out the reason why it leaked. The nail that punctured her tire entered in an angle and when I put the plug  in, it was perpendicular to the tire. So the nail I pulled out still had the gap and leaked. I basically created a new hole and plugged it (red bar in photo) hoping to resolve some darn issue lol. That’s a first!
