So math is NOT my thing. lol I really don't analyze it or break down at all: I go with perceived effort more than anything, and I've been an athlete/dancer all my life, so I suspect I'm better than average at making that assessment. I'd think it would be much harder for a true newbie. I don't stick to any one interval ratio - I've used lots of different combinations and have a good feel for what works for various situations. I'm a natural sprinter and endurance is a real challenge for me, so that influences my intervals. Generally speaking, I use longer run intervals (say, 2:00run/1:00walk) in summer because it forces me to slow down to deal with the heat here in FL, but prefer shorter intervals for cooler weather (1:00run/:30 or :45walk is a favorite.) I like a 1:00/1:00 or :45/:45 for racing because it's easy to skip walk intervals when I'm feeling speedy at the halfway point (I'm totally a second-half racer) without having to do mathI don't have a lot of experience with run/walk, but as @Pleglech suggests the 3-hour mark may not apply in these cases.
My question to those who do use run/walk is how do you determine your intervals? Let's say you're planning on running the marathon at 16:00 min/mile. It looks like Galloway suggests for a 16:00 min/mile you are to do 10 seconds running / 30 seconds walking. This would mean during a 16:00 min/mile there would be 24 interval sets. You would need to run a distance of 0.04 miles per interval set to complete a mile. Assuming an average walking pace 20:00 min/mile, after 30 seconds of walking you have covered 0.025 miles. This leaves 0.015 miles in 10 seconds or a pace of 11:11 min/mile. Does this sound correct?
So, since you're training for a 16:00 min/mile marathon pace, presumably 80% of your training should be at or slower than long run pace. Long run pace for someone training for a continuous 16:00 min/mile would be around 18:00 min/mile. So, do you adjust your training paces as well to an 18:00 min/mile run/walk interval? To me, it seems like you are already accomplishing the 80% since 75% of your long run is at 20:00 min/mile (below the 18:00 min/mile).
@PrincessV What do you do during the rest of the week beyond the long run?

I do a 2-week cycle that looks more or less like this:
Mon: speed or hill run (generally around 2 miles)
Tue: 45 min run
Wed: Pilates
Thu: 4* mile run - (this is in prep for doing the 10K and full in January - so that 4 is increasing up to 5 next week)
Fri: rest
Sat: long-long run - easy pace, pickups last few miles if weather permits (last one was 17 miles in 4:17:00 - I had a gazillion stops for red lights and water refills, and it was pushing 90* toward the end so I walked a lot of the last couple miles of that one.)
Sun: rest
Mon: yoga
Tue: 50 min run
Wed: Ballet
Thu: 4* mile run
Fri: rest
Sat: cut-back long run (8 miles now)
Sun: yoga
