I decided to stop, 34 deltaE sounded like a lot of difference.
Right, but this isn't magic. The 34 delta E is to the (loosely) expected value (ie. the value I read on one of my charts when I created the .ti2 file). How did you decide that this wasn't a mis-read that a retry would correct, or that your chart really is expected to be very similar to the expected values ? Graeme Gill.
