BERL’s main response thus far is that my critique hinges critically on strict rationality assumptions. Of course, I’ve rebutted that more than a few times, most thoroughly here. Follow the “BERL” tag there for the whole sordid affair.

We’re going to put up a revised/corrected version of our paper end week or early next week to incorporate the bits at the top. We’ve asked Adrian Slack if he has any other bits where he’s pretty sure we’ve mucked up (entirely possible since we had no access to any of their underlying workings and their paper is opaque at best in parts). We’ll see what else, if anything, they have to recommend after having now had more than three weeks to look it over.
