Patience
If guys don’t respond quickly, don’t worry. First, maybe they agree what LIL has said and have no more to add. Second, perhaps you haven’t given them a chance to even read your post yet.
Remember, not eveyone has the time or possibility to spend hours a day on the forum. I for example can rarely post on the weekend, which leaves me a lot of catching up Monday morning which I really need to organize my working week.
As far as your post goes, it is clear you are referring to three sessions (I just wanted to clarify that each session was not 40 mins straight). And I can’t add much to what LIL has said, except that once you are hanging well, and more experienced, the more time the better IMO, allowing for rest days and obviously not over doing it.
So, more sessions less sets, or less sessions more sets. I say more sessions more sets, but using common sense.
