I have set up an LCI where each input is multiplied by a parameter (let's say input_1 x a, input_2 x b, and input_3 x c). I want to set each parameter to 1, then 10% less than 1, and 10% more than 1.
So:
a=1, b=1, c=1 then
a=0.9, b=c=1 then
a=1.1, b=c=1
I do this in both python and the openLCA project tab. I have two problems now:
1) When I compare python and openLCA LCIA results, the values are different. There is no common factor in the differences and the differences are quite large:
-> settin a=0.9, b=c=1 from openLCA does not equal settin a=0.9, b=c=1 from python
2) I was expecting the changes to be linear
-> the difference between a=0.9 and a=1.0 does not equal the difference between a=1.0 and a=1.1.
Can you assist?
