Since your strength in a particular exercise is both neurological and muscular, it would be logical to seek an optimal point of a repetition number where the two meet, or use a variety of rep ranges that cover both like 5/3/1. But what will happen if you exclusively train near the 100% region? Based on the premise, logic dictates that it would be suboptimal, but has anybody tried that before? Bulgarian weightlifters at first seem to train exclusively near their max capacity, but it's not the case if you look at their training log. They ramp up the weight and also employ drop sets.
Regarding the optimal point for strength gain, I'd like to mention that based on this study, a hypertrophy vs rep range curve probably would look like a normal distribution curve, but I imagine that a neurological gain vs rep range curve would probably have a "left side bias" (it favors very low number of reps). So an optimal point for strength gain would probably exist in the low end of rep ranges, something like 4. Wow talk about reinventing the wheel. Actually I just want to make clear what I'm talking about
