Default %Change to AFR Ratio Table Question!

Ok, there are two tables to control the amount of enrichment the AFR gets at WOT...they are:

%Change to Fuel/Air Ratio vs. RPM at WOT
and
%Change to Fuel/Air Ratio vs. Cool. Temp. at WOT

Both of these tables show enrichment to add fuel at WOT of course...my question is:

Does one table compound onto the other OR, does one table REPLACE the other when values are met? For example, If I have 7.7% enrichment in the 80*C block on the %Change vs Cool. Temp Table, and then I have 3% enrichment in the 4800 RPM block on the %Change vs RPM table, does that mean that at 176*F and at 4800 RPM's my ACTUAL AFR enrichment is 10.7% at WOT for those blocks??? Or does the RPM table take over once its conditions are met, so say it runs 7.7% up until 4800 RPM's, then it drops to 3% until another change happens, or vice versa??

They are added together. Usually in the normal operating temp there is no enrichemnt from the cool temp table.

Leave the temp table stock and make your changes in the rpm table. Unzip this file and copy and paste the rpm table values into it.

Here is the Excel file unzipped. Change the .txt extension to .xls after you save it. Cant upload a file with a .xls extension here.
