It's the new 'stop condition', we now have 4 in Iray.

It's a different way of calculating (and predicting) convergence. In practice it's highly scene dependent. For my scenes, on average it reaches convergence quicker with around 80% of the iterations required by the 'old' convergence, but you may be doing very different kinds of scenes than I do.
