exposure tables: slides vs. prints

Kodak's exposure tables for print films read one f/Stop more than for their 
slide films. 

For instance Kodak Webpage tables (or those inside the filmboxes): 
BrightSun/distinct shadows is 125@x/11 Gold ISO 100 printfilm, but is 
125@x/16 for Elite ISO 100 slidefilm.

Seems to me that Kodak must set both films to an ISO value of 100 for use 
when the light is being measured reasonably accurately, such as when using a
lightmeter. But for use with less exact methods (when shooting from just 
using the published tables) then Kodak fudges the tables to make sure that 
slide film users err more often on the side of underexposure as compared with 
print film users.  

To me the above seems likely, but cannot figure out this: which table is 
Kodak fudging, the slide table, the print table, or both?

In other words for the sake of argument suppose that both types of film 
actually gave exposure latitudes which were identical to each other and also 
equal in either direction (overexposure/underexposure). In that case, I 
wonder which table Kodak would publish: a table like their current print film 
table, one like their slidefilm table, or one half way in between?
