Statistics during the course of phasing. The expected value of the shell correlation coefficient <C> = $[\textstyle \sum_{{\bf h}\,\,{\rm in\,\,the\,\,shell}}[F_{\rm obs}({\bf h})]^{2}m({\bf h})/]$ $[\textstyle \sum_{{\bf h}\,\,{\rm in\,\,the\,\,shell}}[F_{\rm obs}({\bf h})]^{2}]$ versus the resolution shells is shown after one, six, 11, 16 and 21 cycles of phase calculation.
