What about the beginning? It doesn't add up.

Just watched this movie. Fascinating. I have seen Triangle also and have debated it to death (though a long timen ago).

In contrast to Triangle we know thatr this loop must have had a beginning, since the scientist talks about them agreeing on this experiment. But how can this be? The first time Hector gets send back to the past there would not be a first bandaged Hector to stab him in the arm. And so it would not make sense for Hector 1 to recreate this stabbing in the following loop cycle. In other words: this loop cannot have a beginning without the alterations being different.

Another problem is that when Hector sees himself coming home, this Hector at home is ALREADY send back in time since we have witnessed the beginning of the loop from this point forward. This means that when Hector sees himself for the first time there already have to be 3 Hectors around.

Also, when one goes back in time 1 hour, this would mean that from that first moment every next hour a new Hector would be "born." Eventually this would mean alot of Hectors.

Still thinking about it, but something does not add up, though the loop cycles are cleverly done.
