I will try to work on a better explanation of the decel and accel tables in the help. The dTPS trim you see is the TOTAL accel fuel due to change in throttle.
You have a base table, and then "factor" tables that will add to that table depending on certain conditions (load, RPM, TPS).
The
base table is "dTPS BASE TIF ECT TABLE" and the
factor tables are "dTPS TPS FACTOR TABLE", "dTPS RATE FACTOR TABLE", "dTPS RPM FACTOR TABLE".
So what happens here is you start with your base table value and then you will multiply that table by all of the factors from the rest of the tables.
So say you base table is 5.4 msec and the factor tables are all 100% .. then your dTPS fueling will be 5.4 msec.
If you base table is 5.4 msec and all of your tables are 100% except your "dTPS RPM FACTOR TABLE" is 50% .. then your dTPS fueling will be 2.7 msec.
I will write a much better explanation for the help section, but that is a brief overview.
@OnTheChip might be able to elaborate a bit more.
