The tax table and the tax computation schedule might bring different end results due to the timing of publication of one versus the other. I have found over the years that there have always been slight differences. Provided this slight difference does not put you into a higher tax bracket then I would not spend time on it. For example, if you are talking $1500 difference and that $1500 brings you to a 32% tax bracket versus a 24% then I'd definitely make sure the end result puts you into the 24%.
