DateDiff Function between changing variables

I am trying to calculate the time difference between conditions.

The workflow is as follows, there is a job created (Prim_ID_Fk) and everytime the job process changes it writes to a track table that adds the Prim_ID_FK as the job,  it adds a new process description and a time stamp when the job changed.

 

Is there a way to show per job the chagne from the old to the new job description and the time difference from when it was updated?

There is 11 Job processes:

Despatch, Prewash, Strip, Assesment, Quote, Go_Ahead, Wash, Assembly, Test, Spray, Despatch/Deliver

These description can exist in any combination

 

I would like to show:

 

Prim_ID_FK |  Process (Last) | Process (New) | Time |

1                    Despatch          Test                   02:10

1                    Test                   PreWash           01:15

1                    PreWash           Spray                00:25

2                    Despatch          Prewash            00:45

.......         

 

DIFF = 
    VAR Current_Job=LASTNONBLANK(aas_wf_track_tbl[Prim_ID_FK],[Prim_ID_FK])
    VAR Current_Date=MAX(aas_wf_track_tbl[Track_Date])
    VAR Current_State=LASTNONBLANK(aas_wf_track_tbl[Process_Description],[Process_Description])
    VAR Min_Date=SWITCH(Current_State,"Despatch", Current_Date,"Despatch",MAXX(FILTER(ALL(aas_wf_track_tbl),
        [Prim_ID_FK]=Current_Job&&[Track_Date]<Current_Date),[Track_Date]))
    VAR Max_Date=SWITCH(Current_State,"Despatch",MINX(FILTER(ALL(aas_wf_track_tbl),
        [Prim_ID_FK]=Current_Job&&[Track_Date]<Current_Date),[Track_Date]),"Test",Current_Date)
    RETURN
    DATEDIFF(Min_Date,Max_Date,MINUTE)

do these processes only ever travel from left to right ? or can they move backwards etc ? also Is this in a table, I have a soultion for this in Query Editor that we used for field status. 

 

Thanks

It can go left to right the order can change, thinkt hat is the one thing that makes it more difficult because of the permutations, it can also skip a stage.
