Mean Time Between Failure

I read @Greg_Deckler 's 

 

MTBF Measure =
VAR __table = 'MTBF'
VAR __table1 =
ADDCOLUMNS(__table,"__next",
MINX(
FILTER(__table,
MTBF[WORK_ORDER_NO]=EARLIER(MTBF[WORK_ORDER_NO]) &&
MTBF[ACTUAL_START_DATE]>EARLIER(MTBF[ACTUAL_START_DATE]) &&
MTBF[JOB_CODE]<>"PM"
),
MTBF[ACTUAL_START_DATE]
)
)
VAR __table2 = ADDCOLUMNS(__table1,"__uptime",
IF(MTBF[JOB_CODE]="PM",
0,
IF(ISBLANK([__next]),
DATEDIFF(MTBF[ACTUAL_FINISH_DATE],NOW(),DAY),
DATEDIFF(MTBF[ACTUAL_FINISH_DATE],[__next],DAY)
)
)
)
VAR __repairs = CALCULATE(COUNTROWS('MTBF'),FILTER(ALLSELECTED('MTBF'),MTBF[JOB_CODE]<>"PM"))
RETURN
DIVIDE(SUMX(__table2,[__uptime]),__repairs,BLANK())
 
Thanks in advance for any help you can give me.
