Snippet: As shown in Table 2 , after Feb 3, death number (350) were more than Jan 21 case 158 number (270), if the T was 12 (Feb 3 minus Jan 1), the CFR would be illogically greater than 159 100%. In another words, death numbers only when before day 12 were less than case number 160 at day 1. So the time T should be less than or equal to 11 days (12-1). The death number when 161 was firstly more than the case number at day 2 was Feb 5 (day 15), so the T s.....

The death number when 161 was firstly more than the case number at day 2 was Feb 5 (day 15), so the T should be less 162 than or equal to 12 (14-2). The rest could be done in the same manner. Finally, the smallest T 163 value (T = 11) was selected as the upper limit for convergence screening. 164 Figure 3 was the calculation of daily CFRs with assumed T values (0 to 11). When 165 assumed T was 8 to 11, daily CFRs were continuously decreasing. When T = 0 and 3, there 166
