Custom KPI based on multiple parameters

Hello,

I have a requirement to create a front page based on the comparison of multiple stages(in my case there are 6) based on the Region and Field value.

The model looks like(only 1 table is there):

The matrix I have created in the detailed view looks like:

Now on the front page, I want to show a consolidated picture or like an indicator that would show me green if the difference between the volumes at each stage is same, as in S6-S5,S5-S4,S4-S3,S3-S2,S2-S1 is 0, then green

otherwise red.

If it is red, it should show a quick visual for which region and for which field value the red value is showing.

I tried something based on guy in a cube video-https://www.youtube.com/watch?v=zHzSBNES6jE&t=337s

But I am not sure, how should I be able to compare the volumes of different stages keeping the Field Value and parameter in consideration as part of the calculation.

Probably I am not doing any justice to this :

   Does have any leads to implement it or any better idea where I can present it in a much better way?

Thanks
