Research continues. We haven’t made any improvements to the underlying model for some time, but we are working out some bugs in our metrics. The hope is that the improved metrics will narrow down some new areas to explore. It is just as likely (or maybe even more likely) that the metrics say nothing new or meaningful, in which case we are back to square one. The paths in front of us are shrouded in darkness. My experience, which has taken me thus far, has no bearing on these new possibilities. What should I do?
