I have a problem with my conseutive days counter. I visited the site every day in the last two months. Yesterday the counter showed 62 consecutive days. Today I see 2 consecutive days on my profile page. How can be this possible?
Are you sure there was no more than 24 hours gap between your logins/visits?
Consecutive days are calculated on the basic of GMT days, so if you don't measure time in GMT, it's safe to assume that day is each subsequent 24 hours period.
On the margin, it would be more fair, it the algorithm would measure the time gap between logins/visits.
