acording the the data number of breakdowns would be 8 and number of operational days would be 17

 

is there a DAX formula that would easily go through a list such as this generate these numbers for me

Amazing thank you so much, only adjustment to the Formula would be subtracting 1 from the result

 

new column =
var _max = maxx(filter(Table, [Truck] = earlier([Truck]) && [Date] <earlier([date]) && [Status] ="Out of Service"),[Date])
return
if( [Status] ="Out of Service" && not(isblank(_max)), datediff(_max, [Date], day)-1)

@Anonymous , you can create a column like and use that for avg

 


new column =
var _max = maxx(filter(Table, [Truck] = earlier([Truck]) && [Date] <earlier([date]) && [Status] ="Out of Service"),[Date])
return
if( [Status] ="Out of Service" && not(isblank(_max)), datediff(_max, [Date], day))
