It's kinda simple in reality. More volume is better ONLY when it's not slowing the rate of progression on the mechanical tension aspect. for example, if A is progressing at 5% every week (strength wise) with 10 sets x week and we increase his volume to 20 x week and he is STILL progressing at at least 5% every week, then more volume here is better (at least in the SHORT TERM..). But if subject B progress 5% every week at 10 sets x week and at 20 he is just progressing slower or not at all, then lower volume is better. The key is the highest volume with which you can progress the most, and probably a little lower (for reducing injury risk and for increasing the time that occurs every time before approaching the overreaching state, before having to take a deload).
That's the thing, in every Schoenfeld study or whatever, the subjects, even with that high volume, are still increasing weight/reps every week on the exercises (for whatever reason, it can be more motivation, more rest, whatever), even in the last "45 sets to failure x week for quads" study! BUT if it isn't the same for you, then all you are doing is losing time doing junk volume, overreaching sooner and increasing injury risk tenfolds. If those subjects didn't manage to increase their strength, i can bet they would not realize that much hypertrophy, probably lot of edema, intracellular water, increased glycogen storages, etc.. (sarcoplasmic hypertrophy we could call it).
In practice, if a subject is not progressing in strenght (weight/reps/..), then all that high volume is useless. Much better a lower volume approach. It's always been the art of finding that sweet spot for that particular subject, there is no fucking perfect number of sets x week for everyone, it's impossible, there is no fucking need to study it again, and all the inter variability in muscle hypertrophy response during these such studies demonstrated this very clearly.
