Just above the graphs there is a small table of credits per project. There is a column last day. Shouldn't this total be equal to the sum of my individual hosts ?

For example, May 7th, PrimeGrid shows a total of 45.59 credits on my detail stats page. All my individual hosts say 0.0 credits. I went over to the Primegrid and those 45.59 credits seem to be received on the 6th, if I sum up on what is reported on the PrimeGrid site. For the 7th I have received no credits. So the host pages show the correct value, but my detailed stats page, shows a wrong value.

Antoher example is Einstein. In my personal page I have 377.15 credits for the last day. That same amount is reported for one of my hosts. But there is a second hosts that reports 181.40 credits for the last day. Going to Einstein's site and counting on what has been received. The individual hosts stats are correct again. So again my total on my detailed stats page is wrong again.

User/team/country stats and hosts stats are not updated at the same time. The daily update for users/teams/countries is 12 hours before the host update. Therefor there will be differences.
