Ah, very helpful. My sense of "normal" was probably developed back when I was doing a 500+ day streak, which ended a few months ago. During the streak, I would generally check my stats daily in the evening my time (mid-evening US East Coast time). But I cannot get out to cache as often as I used to, and so I am not checking stats daily, and it is possible than yesterday I checked stats during the day, thereby triggering the 24 hour clock. Thanks.
