Hi  @Narendra90 ,

Here are the steps you can follow：

1. Create calculated column.

Output1 =
var _date1=
MAXX(    FILTER(ALL('Table'),'Table'[ID]=EARLIER('Table'[ID])&&'Table'[Rating]=EARLIER('Table'[Rating])),[New date])
var _date2=
MINX(    FILTER(ALL('Table'),'Table'[ID]=EARLIER('Table'[ID])&&'Table'[Rating]=EARLIER('Table'[Rating])-1),[New date])
var _value=
  DATEDIFF(
        _date2,_date1,DAY)
var _count=
COUNTX(  FILTER(ALL('Table'),'Table'[ID]=EARLIER('Table'[ID])&&'Table'[Rating]=EARLIER('Table'[Rating])),[Rating])
return
IF(
    'Table'[Rating]=
MINX(
ALL('Table'),[Rating]),0,
_value / _count)

2. Result:
