Beating the closing number feels like proof you were right. It is only a clue. Prop closing line value tells you something about the quality of the price you took, and nothing about whether you cashed. You will separate three tests: forecast quality, price quality and realized execution. A worked example takes an over 5.5 receptions bet at +110 that later closes at -110, and shows why the 4.76 point gap is not profit and not proof of edge. You will learn to compare the identical stat, threshold and settlement rules, use a no-vig closing benchmark, and avoid comparing a 5.5 quote to a 6.5 close.
