Can rarely get John Hopkins to load, usually crashes/way too slow whenever I try it.Every other source? Maybe try John Hopkins for a start. Clearly they arent getting it direct from state health departments, because all of the other sites reporting they get it straight from health departments have different numbers.
Beyond that, and I can only speak for my state, they arent smart enough to realize it only updates once a day and instead they check the numbers 4 times a day.
Checked my state California - 106,878 total cases 4156 deaths which exactly matches state figures here https://www.cdph.ca.gov/Programs/CID/DCDC/Pages/Immunization/ncov2019.aspx
Florida they are currently reporting 55424 cases and 2530 deaths which for cases matches the Florida dashboard https://experience.arcgis.com/experience/96dd742462124fa0b38ddedb9b25e429/. There is a discrepancy on the deaths ( state dashboard is 2477) but there is a note “We report using the raw data provided by FDOH but we include both Florida residents and non-residents. On March 26, the dashboard stopped including non-residents in its visible counts, but they're still tracked behind the scenes.”
Checked Arkansas and that also lined up for case #s
Can you point to the state(s) you feel their data is inaccurate for?
