I'm not so sure about 4 revolutions! ok, I know that before the first patw people didn't think it would be done, but I'm pretty sure that the people that could do latw at that time could do 2 and a half revolutions, but those who can do patw now can't easy do 3 and a half, and the latw technique is different from the patw technique! if your doing a patw you need to jump a bit later, if not it's to hard to do the last round, and if you're going to do 4 revolutions then you need to jump later than that, and then you maybe need to wait with the jump until you're finished with the second revolution.
I think it's to hard. Maybe I'm saying that because I've done patw and I feel like I'm NEVER gonna do 4 revolutions myself, but Maybe szymo, Azun, zegan, fx...... feel like they can do it, but personally I think it's to hard because of the technique.
