I found your initial post and title quite negative and would have responded better to an actual question. I'll cover this until Kim answers.
Arthur made very, very few comments about specific paces. He once told his guys that if they were running the 22 mile Waitakere course in more than 2:20 they were wasting their time. That would be slower than 6:30 pace for guys capable of running marathons at under 5:30 per mile. Peter Snell told me that he recalls doing the runs at about a 7 minute pace at the start of base training and that the pace would drop to a bit above 6 as the season went on. But he emphasized that the level of effort was the same. In other words, you went faster because you'd gotten fitter, not because you were working harder.
Barry Magee was briefly the South Korean national distance coach until he gave up the job because he couldn't stand the food in Korea. He was given all of their top marathoners, the slowest had done 2:25, many were much faster. He sent them out for a 20 miler and gave them the "best aerobic speed" talk before the run. They all ran the course in 2 hours, much harder than he wanted them to. He told me that to get them to run the proper speed he had to tell them to jog.
Eventually, Arthur moved to a system of running for time rather than for miles and advised runs of two hours or more but was NEVER specific about the distance one should cover in that time. He once told me never to worry about minutes per mile but to go out and enjoy my runs.
I think this gets confusing for people because he was always telling people not to worry about going fast and then getting angry at people who described his system as one of long, slow, distance. He never liked the idea of LSD, but also insisted that you should be comfortable on your base building runs. It's probably a hard adjustment to make for people who've grown into the sport while being told to run x minutes per mile on long runs, y minutes per mile on "recovery" runs and z minutes per mile on intervals. But the realtionship between marathon times and pace for long runs is very loose in his system.
