Submit them right now. I missed a "priority deadline" for a program due to being a perfectionist and having high anxiety so before the general deadline I went somewhere that wasn't my house, opened a work doc and said "I'm not leaving here until I submit whatever I have". I wrote, read it aloud, made some edits, read it through once more, and submitted it within 2 hours, and I got an interview at that program. Was it my best work, no but it was in. You can do it too, just tell yourself done is better than perfect. You may have a 3% chance with a late app but you have a 0% chance without one.
