Schedule Logic too Difficult for me

[Britz]

what i want to setup is so that

7:00am - 19:00pm mon-fri use failover
0:00am - 7:00am mon-sun block
19:00pm - 23:59pm mon-sun block
7:00am - 19:00pm sat-sun use single gateway

so seeing as schedule logic works as
pass turn into block
instead of pass just being ignored and then looking at next rule

so i have given it a lot of thought and i am stumped i just cant figure out how i can setup the above mentioned gateway usage using current scheduling logic

i understand i will need 4 rules

1 blocking nights
1 disabled blocking sat-sun days
1 allowing failover mon-tue
1 allowing single gateway sat sun

i can for the life of me not figure out the order those 4 must be in

please help
thanks
