Count Consecutive Days while bridging over days off and holidays

Though the logic appears valid and it yields the expected results I am not particularly confident of this one.

Array entered in K2 / filled down.

=SUM(IFERROR(((TRANSPOSE(C2:H2)={"MIAOUT","MIA","UPTO"})+(-1*(TRANSPOSE(D2:H2)={"","<>DAYOFF","<>HOLOFF"}))),FALSE))+1

Edit: TRANSPOSE was unnecessary. Loose ends from the build. My bad. This instead.

=SUM(IFERROR(((C2:H2={"MIAOUT";"MIA";"UPTO"})+(-1*(D2:H2={"";"<>DAYOFF";"<>HOLOFF"}))),FALSE))+1
