This is pretty amazing and interesting for me! Which of them (total or quarter) is actually the correct one? This picture was taken on 7th June 2015, 9:00 PM (GMT +5:30).
See here on Meta.SE.
The discrepancy is by design:
- Total reputation is your current reputation on the site (accurate to within 24 hours).
- Month reputation is the amount by which your reputation changed that month, excluding "private" reputation events. Certain reputation events are excluded from your public user profile, such as deleted posts or downvotes, so those are excluded from the leagues as well.
In other words, "total reputation" includes private reputation events, while "month reputation" does not.
