The additional information is me being responsible and also stating that even though initial tax cuts will spark revenue increases, there is a point that addition or subtraction of other economic policy will need to be injected to steer the economy further. Thanks for muddying the water though.

If you're on the left side of the peak of the laffer curve, tax cuts will decrease revenue roughly in proportion to the cut.
Economic growth could work in the opposite direction, bringing increased revenue.  A tax cut often stimulates economic growth in the short term.  But the growth may not be as strong, as a percentage, as the cut was, again as a percentage.
And any tax cut that was done for temporary stimulation should be rolled back once the economy is healthy again.
And in order to find out if it might have worked, you have to adjust the raw numbers for inflation.
And even after you've done all that, all you have is a correlation.  It was not a controlled experiment.  You can not prove that it always works that way.
