The thing about being orthodox is that it cuts way down on innovation and can stuff an athlete into a box that maybe isn't the best fit for him individually. All of what we read about training and race preparation now suggests a particular model that's "correct" (yeah there are various takes on what "correct" is supposed to look like) and the idea is to have the athlete follow that model.
But the idea here is that by and large everyone will respond optimally to the model. It doesn't really allow for individual differences. The art of coaching, or of self coaching, is not just about learning all these good ways to train and maybe about the physiology behind them, but also learning about the individual athlete.
Lydiard used to prescribe a hard marathon time trial three weeks before your marathon so what Albertson did is not unprecedented. Over time people got away from doing that at the full distance but good marathons have been run that way. Yes, for some people it's probably too hard and too close to the race but there are likely some people for whom it's a good idea. And the only way to know if something like this is a good idea for a particular athlete is to try it.
Maybe it flops, maybe it goes great, but either way you've learned something for future races. But a lot of people who post here with their ideas and critiques of other's training and racing don't seem to understand anything other than what they learned from reading things like Daniels, some articles, etc. so you find posts where people will look at guys like Ryun or Clayton and say "Think how fast they'd have been if they'd trained properly."
