OK - It's NOT by any means pretty, but I have managed to get the effect I
want using...


 CDEF:drn1=LTIME,172800,-,604800,%,172800,LE,0,LTIME,86400,%,10801,32400,
LIMIT,UN,0,cpu,IF,IF \
 CDEF:drn2=LTIME,172800,-,604800,%,172800,LE,0,LTIME,86400,%,32401,64800,
LIMIT,UN,0,cpu,IF,IF \


Any kind soul want to simplify this?
