Default Timing advance on 01-02

I think the advance is a little different on 01 and 02 cars than on 98-00 right? It looks like it starts around 15 and works up to 19*. But I dont understand how it is commanding 19 at the top and showing on the scanner 27 or so?

Is there a multiplier I am not aware of?

For example, in HPT at 100 MAP 5200rpm the table might say 19*

But at that same cell when scanning it shows advance of 26-28.

WHY?

I don't know if the '01+ are that different than my '00, but I know my HO WOT map says 28* up top, LO WOT says 19*.. sound normal?
