Yeah. I don't see much value in the second rep of a double @ 5RM/85% because
1) most folks are getting 100% recruitment at 85%/5RM
2) The second reps are actually quite fatiguing over the course of the session and they limit total session rep count
3) I don't think that second rep in a double is very good practice for mechanics/aggression, etc (if you want RPE 7-9 reps, just do heavy singles).
^ For loads over 80%/8RM, I really like a timed session format. I'll warmup really well, then set a timer for ~20 mins and crank out singles, resting long enough to keep RPEs in check and mechanics really clean.
Thanks. What do you as the value of the super light, low fatigue session @ 15RM?
There's utility value: super light, low fatigue work is something I CAN do when I'm fatigued. And it's low cost in terms of inducing fatigue.
I don't think this load range is inherently better than other intensities for hypertrophy and strength. But - given a state of reduced readiness / high-fatigue - I think it's perhaps the best/most-useful loading range.
I'm very much in support of matching session design to real-time readiness states (autoregulation of the cycle itself).

In terms of stimulus and physiology, the honest answer is I don't know what's going on. And I haven't touched the literature on this in about 2 years.
I'm VERY confident these loads transfer to 1RM (for me). But any justification beyond "because it transfers to my 1RM" is speculation.
I DO think 65-70% (15-12RM for most folks) is a sort of goldilocks zone in terms of bar speed: 1) the bar moves fast enough so peak transient force is VERY high, but 2) load is heavy enough (and bar slow enough) that the contraction velocity is still really, really slow compared to max contraction velocity (so concerns about actin-myosin crossbridging are (kinda) moot).
^ This loading range definitely doesn't work for some folks. I think folks with lots of lifting experience and/or athletic backgrounds tend to get better transfer from light loads to 1RM (just better at accelerating shit).

TL;DR: I think low-load, low-fatigue (but high peak force/power) is almost as good as traditional hypertrophy formats for hypertrophy, but far superior for transfer to 1RM (given the athlete is effective at recruiting muscle absent high external load).
