    There is one instance in which data points do appear on the very steep segment of a Type 1 curve (Pittendrigh and Bruce, 1959, Figure 8). However, the raw data (Pittendrigh and Bruce, 1959, Figure 4) shows that these dots represent multiple recurrences of the monitored event during an interval of transient irregularities.Google Scholar
