Isn’t it possible that a Current never gets judged based on luck of the draw?
Yes. However, it’s not important that the Claim is actually judged, but rather that the market participants believe that judgment will happen. The more certain it is that judgment will happen “soon”, the less likely that bubbles and other price anomalies will occur. It is easy to program in the most effective value for “soon” by tweaking the parameters in the judgment process and seeing how the market reacts.
