About SN80 OpenRoboto
Tasks rotate out when they stop separating models — when everyone clears them, or nobody does. A task like that no longer changes anyone's result, so it leaves. Replacements are drawn from the Axis library: 6,000+ tasks, growing as Axis collects more. Each round's set is drawn, frozen, and published with a version number before submissions open. That makes overfitting extremely difficult here. You can overfit one round. You can't overfit the library — a model that clears 6,000+ tasks across every category has, in fact, generalized.
