I can understand that at times DAX can be really cheeky and takes a lot of time to process the logic. The best way i break down a logic from Sam’s video or from any dax calculation logic video/article is to break it in to pieces.
I hope you have heard of the Dax studio if not than download it from here
I would say spend some time on it . You can watch these you tube videos as how to use it.
Also, whenever you try to break a dax code to understand than always start from inside out .
Hope this help. Further, if you don’t understand any specific part of the above mentioned formula i will try to explain.
One option might be to create a new table with Customer groups and use DAX for min and Max. In other words split this formula. In some cases, split helps in developing understanding but downside is more formulas make difficult to create visuals. There is always a balance.
