I think this is 5.147.5.3.147.3.147,147

Your composition works, but I typed it in wrong the first 
time and found that replacing the final P with C 
in parts 6,12 and 18 also works (or have C at the end 
except P in parts 6,12,18).

Also
X,P,A,P,A,P,P,A,A,A,P,L,D,B,B,A,D,P,A,D
then replacing the last D with P in parts 6,12,18 works.
It has fewer plains, but fewer types of call.
