Somebody calling himself Mr. Ed should not beat horses -- even dead ones.  
Nevertheless...

I think PoA is a great book -- and just as I suspend my understanding of the

the time travel sequence.  But peoples' explanations sometimes confuse me.

But to keep the statements consistent, don't we have to accept that if 
something went 'wrong' it cannot be changed.

In this particular incident, Dumbledore says to Harry and Hermione that MORE

term, didn't Dumbledore indicate the goal was to make something change?
