I am no grading expert by any means but have had a couple thousand cards graded in the past few years. Any time I have gotten back an altered stock card (3 or 4 cards) it was because the card at some point in it's life was in a heavy screw down holder. The holder by putting pressure on the card can leave tell tale wrinkles that I think any TPG will detect. So submitting it to a different TPG has never worked for me but only tried a couple times. (then someone who worked for a TPG explained why they came back with altered stock). AND YES I know that there are other reasons why a card can come back altered stock but in my experience only reason my cards came back with grade. Hope this helps
