The below works, but can it be more efficient?

What I'm doing is on a daily basis copy the equations over a column, range
"value", "Yesterday" results (so those results don't change) and then bring
in the new daily data.

if nothing else I think that I should remove the 5 and 33 with range names...

Sub DAILY()
Dim LastCol As Long
With Sheets("WeeksDetail")
LastCol = .Cells(5, Columns.Count).End(xlToLeft).Column
.Cells(5, LastCol).Resize(33, 1).Copy .Cells(5, LastCol + 1)
.Cells(5, LastCol).Resize(33, 1).Value = .Cells(5,
LastCol).Resize(33, 1).Value
End With
ActiveWorkbook.RefreshAll
End Sub
