No, since I expect our next batch will be our best yet. That said, your point is true in two ways (though I don't think in the way you intended it). First, we try to make every batch better than the ones before it. That implies that it's always better to come to a later batch (I think it's certainly true that it's better to come to Hacker School today than a year or two ago). Second, every batch has been an experiment for us: we make lots of changes (big and small) and we never know a priori how well they'll work.
