How to calculate Difference from Base Line (like FireBase in AB testing)

Hello Every One,

I am newbie in Power BI

I want to controll all Firebase AB testing of all projects in a dashboard. 

- I get all data from Bigquery 

- I mark 0 is control user, 1 is target user

My table like: 

When I calculate % Difference Experiment with baseline but I cannot get valid result

Current solution: 

- Make base table from origin table relationships is ID_AB_Unit:

Then calculate base revenue from base table, calculate experiment revenue from origin table -> DIfference revenue. It seem like working but wrong when I filter by version in origin table  

Any idea with this situation?
