Query: Incetive Compensation (OIC); Multi-dimensional Rate Table Useage

Question

Hello,
I have a compensation calculation scenario, where the outcome for a plan element takes the outcome of multiple preceding plan elements as factors in calculating the earnings factor. I'm trying to understand the mapping between dimensions of the rate table and data used against them.
To elaborate :
1.) I have plan element one which calculates the total units sold on a particular product.
Plan Element PE1 (intermediate calculation) -
Input = count of units from orders, with eligible products
Output = Input
2.) I have another plan element which calculates the revenue attainment from eligible products
Plan Element PE2 (intermediate calculation) -
Input = SUM (Transaction Amount) from eligible transaction (products)
Output = same as input (output not significant here)
Performance = (Input Expression) / Goal
3.) This third plan element calculates commission based on the outcome of the above two plan elements
Plan Element PE3 (commission calc) -
Input - Expression 1 - Commission Payed from PE1 (same as output from PE1, as no rate table there)
Input - Expression 2 - Performance from PE2
This PE has a rate table defined on these two dimensions:
Perf -> 0% -80 % 80 - 100 % 100% - 200%
units
below 100 5 % 10 % 15%
above 100 7 % 12 % 17%
Output - Rate Table Result * ( Fixed Amount )
My question is, when we have specified multiple input expressions for a formula, does the engine take :
-> outcome of the input expression(n) to be the amount used for dimension(n) and
-> outcome of input expression (n+1) to be used as amount used for dimension(n+1)
so on and so forth ? Is it positional mapping between input expressions and rate table dimensions?
any help is appreciated, thanks
