Case Age formula excluding Statuses

Hi all, 

I have a Case Age in Days that is already set up to exclude weekends. I'm trying to append it to also remove Durations of 2 different statuses. I have a Flow set up to populate the date fields and then I have a Duration field that calculates the status time. How would I append the below formula to minus the two duration fields?

IF( IsClosed,

CASE(MOD( DATEVALUE(CreatedDate) - DATE(1985,6,24),7),

0 , CASE( MOD(DATEVALUE(ClosedDate) - DATEVALUE(CreatedDate),7),1,2,2,3,3,4,4,5,5,5,6,5,1),

1 , CASE( MOD(DATEVALUE(ClosedDate) - DATEVALUE(CreatedDate),7),1,2,2,3,3,4,4,4,5,4,6,5,1),

2 , CASE( MOD(DATEVALUE(ClosedDate) - DATEVALUE(CreatedDate),7),1,2,2,3,3,3,4,3,5,4,6,5,1),

3 , CASE( MOD(DATEVALUE(ClosedDate) - DATEVALUE(CreatedDate),7),1,2,2,2,3,2,4,3,5,4,6,5,1),

4 , CASE( MOD(DATEVALUE(ClosedDate) - DATEVALUE(CreatedDate),7),1,1,2,1,3,2,4,3,5,4,6,5,1),

5 , CASE( MOD(DATEVALUE(ClosedDate) - DATEVALUE(CreatedDate),7),1,0,2,1,3,2,4,3,5,4,6,5,0),

6 , CASE( MOD(DATEVALUE(ClosedDate) - DATEVALUE(CreatedDate),7),1,1,2,2,3,3,4,4,5,5,6,5,0),

999

) + (FLOOR((DATEVALUE(ClosedDate) - DATEVALUE(CreatedDate))/7)*5-1)

,

CASE(MOD( DATEVALUE(CreatedDate) - DATE(1985,6,24),7),

0 , CASE( MOD(TODAY() - DATEVALUE(CreatedDate),7),1,2,2,3,3,4,4,5,5,5,6,5,1),

1 , CASE( MOD(TODAY() - DATEVALUE(CreatedDate),7),1,2,2,3,3,4,4,4,5,4,6,5,1),

2 , CASE( MOD(TODAY() - DATEVALUE(CreatedDate),7),1,2,2,3,3,3,4,3,5,4,6,5,1),

3 , CASE( MOD(TODAY() - DATEVALUE(CreatedDate),7),1,2,2,2,3,2,4,3,5,4,6,5,1),

4 , CASE( MOD(TODAY() - DATEVALUE(CreatedDate),7),1,1,2,1,3,2,4,3,5,4,6,5,1),

5 , CASE( MOD(TODAY() - DATEVALUE(CreatedDate),7),1,0,2,1,3,2,4,3,5,4,6,5,0),

6 , CASE( MOD(TODAY() - DATEVALUE(CreatedDate),7),1,1,2,2,3,3,4,4,5,5,6,5,0),

999

) + (FLOOR((TODAY() - DATEVALUE(CreatedDate))/7)*5-1)
