I look at my BoincStats updates daily. All but the California updates are regular, but California stats haven't incremented for the past 6 days. Details are listed below. My RAC is about 400K units/day. I'm at about 339M credits total, and I'm accustomed to seeing a modest daily incrementation for all my stats, except California, which:

(1) doesn't always change daily, or,
(2) increments % by .00001 Which looks very unrealistic! ,or,
(3) decrements by an amount that appears consistent with 0 credits for the past 24 hours, (instead of my usual ~400K/day)
-------

E.G.,

3/14/19 Ca% not updated in 6 days ***** 99.89552 % Position 824
3/13/19 Ca% not updated in 5 days ***** 99.89563 % Position 824
3/12/19 Ca% not updated in 4 days ***** 99.89564 % Position 822

All other stats make sense, with fairly regular incrementation (except for the obvious Sundays with no updates}.
