I don't believe so, though IIRC, entering in a later time and winning there means you can later go back to it in an earlier one to get a lot of the items over again. So, in theory, going there in the latest possible time (Which is 1000 A.D., IIRC) is technically "best" but other than that it doesn't really matter if you don't care about running it multiple times for more items.
