I think some kind MNetter covered Rawb's explanation of w5 earlier on this thread...
OK copy and paste of a post by AmIOdetteOrOdile follows

Week 5 is an interesting week:
R1 - 5min run, 3 min walk, 5 min run, 3 min walk, 5 min run
R2 - 8min run, 5 min walk, 8 min run
R3 - 20 minute run
Rawbert() tries to deal with the three different days in a single podcsast so it makes it interesting.
As I was doing it today I was making mental notes of what to tell about it, which certainly helps pass the time.
a) there is no one minute warning with the warmup walk. When you hear his voice after it it is to tell you to start running. R1, R2 and R3 start at the same time.
Then it gets interesting! The following is my recollection of the instructions for the runs, and takes the run starting at minute 0
b) 5 minutes: R1 slows to a walk, R2 continue running
c) 8 minutes: R1, your next run begins (NOTE: he does not say ready or go or anything) and R2, you slow down for your walk
d) 10 minutes: R3, you are halfway through
e) 13 minutes: R1, slow down; R2, begin your next run
f) 16 minutes: R1 start running, R2 you are nearly halfway through, R3, about 3 minutes to go
g) 20 minutes: R3, you are finished; everyone else, 1 minute to go
h) 21 minutes: R1 and R2 slow down
i) 25 minutes: R3 your cooldown is complete
j) 26 minutes: starts waffling about his podcasts, neglecting to say that R1 and R2 are now finished.

Sounds very complicated!
