I respectfully disagree, Jim.
If a man runs 300mg/wk for 10 or 20 wks compared to 500mg/wk for say 20 wks, does the HPTA know the difference after its shutdown? Also, i believe that the health and age of the AAS user will determine how easily your HPTA will be restored regardless if you include SERM's, single or double, rather than the amount used. What would a person recommend for a TRT patient who chooses (for whatever reason) to come off after one year of TRT? One SERM? Two SERM's? No SERM's?
My advice for a light recovery plan is to ensure restoration along with the benefits of each SERM depending on the individuals response to 300mg/wk of exogenous testosterone.
Having said that, yes you could argue that a PCT is not necessary. But you would have to have his chart of front of you along with previous experience and related health information to know that for sure. No?
That's my humble opinion and certainly not mean to be argumentative. But, you are the medical professional and i look forward to your reply, big dog.
p.s. since you provided an anecdote, here's one of my own; its like shooting a deer with a .270 and someone arguing that .300 win mag will kill it "better." lol
