That's because there is NO answer to that question because it's a FALSE premise.
It's not about how many works you do - it's about remaining faithful (Matt. 7:19-23, Matt. 10:22, Matt. 24:13, Matt. 25:31–46, John 15:1-6, Rom. 11:22, 1 Cor. 4:4, 1 Cor. 9:27, 1 Cor. 10:12, 1 Tim. 4:1, 1 Tim. 4:16, 2 Tim. 2:12, Heb. 3:6, Heb. 3:12-14, Heb 6:4-6, Heb. 10:26-27, 2 Pet. 2:20-21, 2 Pet. 3:17, 1 John 2:24, 1 John 5:13, Rev. 3:5, Rev. 22:19).
A faithful person lives his life for the Lord - and when he stumbles, he aknowledges his offense to God and confesses his sin because he knows he will be forgiven.
It's NOT about living a perfect life or who has done the most works - but if we don't REMAIN faithful, we cannot hope to be saved.
And as for the ridiculous things you mentioned above - the Catholic Church has NEVER tught that we must walk on nails or flail ourselves or walk on our knees. This is a TEXTBOOK example of why I refer to dishonest people lik YOU as "anti-Catholics" - because you have to LIE to make your points.
