W-4 Update per IRS

Updated my W-4, using recommendation  on the IRS Tax Withholding Estimator, only thing that changes was that an additional withholding of $210 was added to Federal tax. Received my paystub and a total of $462 dollars extra was withheld from my paycheck, so it was super short. I'm I missing something? I compared my last two stubs and only thing different is the federal taxes taken out, and that under additional withholding now shows $210.
