When using an AH divide the Index Error by 2 and subtract or add (depending upon the IE sign) it to the figure you obtain after dividing Hs by 2.
Try using a spreadsheet like this one;

The figures you enter for an example don't have to be realistic but it'll show you that when using an AH the IE gets halved.
