You may want to take into account differences in file timestamps because the data was collated over many days.

Ahh, I didn't notice that. That would affect things. The timestamps and counts are: ('04/15', 630), ('04/16', 1993), ('04/17', 1994), ('04/18', 491), ('04/20', 270), ('04/21', 1049), ('04/22', 59), ('04/24', 33), ('04/25', 342), ('04/26', 29), ('05/03', 165), ('05/06', 86), ('05/07', 23). So most of the members have older join dates than I figured.
