Regridding corners question

I am regridding a 12km by 12km lambert conical conformal grid of sparse emissions over the U.S. To a 1/2 by 2/3 degree grid over the same domain. If a choose the grid corners to be rounded to zero decimal places, I get a slightly different answer in my final emissions than if I round the grid corner to 2 decimal places which is actually slightly (1%) less than the original emissions. Why would this occur, and what is 'best practices' in choosing the grid corners for this scenario?
Thank you,
