It's been my experience that, as a whole, men that train every day (for PE) don't gain as consistently as men that take breaks. Often, men will note a gain after a layoff.
Now, this isn't written in stone for all men. High volume/light intensity training will require that you train more frequently because the intensity is so low. Also, some men just don't respond well to high intensity training, so for them high volume is a must. There's also the matter of imbalances in routines and other variables (health, supplementation, fitness levels, etc.) that should be taken into account to determine training frequency. These factors can make advanced training a bit more complex than the basic stuff.
All other things being equal, "efficiency" should also be taken into account. If you can make equal or better gains doing high intensity, low volume work it would stand to reason that this is the kind of training you should focus on- not just because it's more effective results-wise but because the overall time spent training is usually much less than with high volume methods.
