I’m sure that less variance is better than more variance, but that comes at the expense of more work for the responder. So do we set the number of returned results to 1, with minimal work for the responder and maximum variance? Do we set it to 8, with a nice balance between fairness and responder work? Do we set it to 64, with a huge packet, a lot of responder work and maximum fairness? Or do we let the responder decide and communicate through the challenge, which has some complexity cost?
