The results are no better or worse than 75% of the "other" programs , an intelligently planned 10x3 cycle blows an average HST cycle away - in both strength and size gains. I would not "critique" HST as I feel it has value , but the science is easily dismissed (as it's non-existant) to support SD being anything other than a un-loading period just like any other effective program (and there are literally hundreds) . SD was the only "original" principle , the others have been around and in use for literally decades.
I use HST because it's a break in intensity from other programs that give me better results but that psycologically and joint wise I may need a break from , HST works perfectly for this and still allows for some progress while "taking it easy" , I would never be at the strength levels I currently have with JUST HST , 10x3 push/pull splits hitting each muscle groups 2x/wk have been the most effective scheme I've ever used for size AND strength but I've been doing this 20 years and find that some variety keeps me stimulated mentally and looking forwards to upcoming cycles.
I honestly think HST's a worthwhile program , but blind fanaticism does suggest a lack of experience/education in other systems.

Like I said, it's difficult to discredit the science behind HST or to explain away the results. Experience or knowledge of other programs is not a requirement for HST to be effective.
Let's speak of an unloading period just like any other stimulus. Or in this case, it's a lack thereof. Muscle will respond to it by deconditioning itself just like it responds to a load by conditioning itself. The alternative is that once conditioned, it remains so forever. If that were true, it would be reasonable to expect size gains to remain forever as well. That is obviously not the case. Therefore, conditioning does not remain forever either. What is in contention is the period of time required for conditioning to decrease or to decrease at least enough for a load to stimulate a growth response. Apparently, a couple of weeks of inactivity is sufficient.
Furthermore, we don't know exactly everything that happens to make the muscle resistant to the stimulus. Thus, some of what we don't know could revert more quickly than what we've already observed.</div>
It's not particularly hard to "discredit" HST, at least in terms of its implementation, if not the abstract, science-derived principles. If the effects of (conventionally applied) SD are unknown, at best, then the whole program is suspect as laid out, imho, in terms of "optimizing" hypertrophy in any sense of the idea.
You admit as much yourself, and your only counter-point to this suggestion is that a couple of weeks of inactivity "seems" sufficient? Really? There's research demonstrating that the effects of RBE are lasting for months, and that actual atrophy takes place very, very slowly in trained subjects (in the many weeks to months range). None of this even begins to hint that two weeks is enough, and I don't think the anecdote in favor of HST "working" is any better than most other muscle building systems out there, no offense to my HST bro's.
The basics of HST (progressive load and the whole nine yards) certainly appear "true" as per the research, but the implementation people are selecting to capitalize upon this knowledge (particularly as it relates to the effects of SD) is wholly suspect until we have real evidence that our implementation is doing anything beyond any other progressive load oriented method that's been around for over a century.
Who knows, Bryan may well have this evidence, but if it's out there, nobody on this board has yet presented it.
