Let's begin. First off is we have to recognize, if we haven't already, that when tobi uses s/t ninjutsu to transport himself, he uses kamui.
Ok, now we must understand how the kamui dimension works. If we look at the chapter where it is revealed how kakashi's kunai which he sent through kamui (No, I will not be providing chapters), you can see that the exact place where kakshi sent the kunai through was where it ended up in the kamui dimension relative to tobi's mask. This means that the kamui dimension exist parallel to the real dimension, meaning that for every point in the real world there exist a parallel point in the kamui dimension.
Ok, now we must understand how the kamui ability works in terms of space. This part is simple: it is not possible for kamui to move objects to any part of the kamui dimension, aside from the direct parallel points in the kamui dimension that correspond with the points in the real world. Or at least tobi and kakashi do not have this ability. That is confusing phrasing, so I will give an example. When naruto used the rasengan on tobi's arm, the place where tobi's arm became invisible was the same distance away from naruto's rasengan in both the real world and the kamui dimension. If tobi could change the place where what he transported in kamui went, then he could just move where in the kamui dimension his arm was placed, which would completely evade the attacks. The fact that he doesn't do this is either he can't, he's too idiotic to have realized that he needs to do it (not probable of the tobi we know) or bad writing. If we remove the bad writing variable, it is reasonable to conclude that tobi cannot change the place where things he sends through the kamui dimension goes, and they just go naturally to the parallel points in the kamui dimension. We also know that this travel works both ways because of how Naruto's shadow clone came back through kamui, and was still in the area he had been absorbed, and not just in some random part of the world, seeing as how kakashi would have no way of preventing such a thing from happening if it could, because he doesn't know how it works, having just learned about it.
Now that we know transport to the kamui dimension is parallel, we simply have to deduce. If it is true, as we have proven, that kamui moves you to the exact parallel points of the real dimension to the kamui dimension and back, that means that when tobi uses his space time ninjutsu to transport himself to a new location, he first starts out by transporting himself to the parallel part of the kamui dimension. When he uses kamui to return to the real world, he must use it when he is at the point where he wants to return, because as we have proven, you return through parallel points as well. Which means that he has to travel through the kamui dimension to the point which he wants to go. But we know, or can assume beyond a reasonable doubt, that when tobi uses the kamui dimension to travel, he moves faster than if he were to just run to this point. Therefore it is logical to conclude that when tobi travels from point to point in the kamui dimension, it happens faster than if he were to do the same thing in the real world. The only logical conclusion to take from this information is that time passes faster in the kamui dimension than in the real world. It terms of time, it works the same way as how itachi manipulates time in his tsukyomi, except in the kamui dimension it is (probably) to a much smaller degree and is not controlled by tobi (I assume).
So tell me if I have a flaw in my logic, although I don't think I do. If you cannot find a flaw, then take the knowledge as true and then take into consideration that tobi could trained in this dimension in 6 minute intervals several times a day for years, and could have slightly increased his aging process by doing so, having much more time to train and become stronger.
If you don't understand, dont just flame and say this is wrong. Ask for help understanding, and I or another person who does understand can explain it to you.
