Some of the blacklisted test are double counted and stored in influxdb.
Example below.
Probably there is more of such cases.
We are going to change counting of tests anyway, so not sure if this is worth fixing, but maybe lest keep it to remember.

Example:
"getinflux coin "select id, testCase, testFunction from blacklisted_test where id = '1581596894' and project = 'qt/qtbase' and target_arch='ARMv7' and target_os_version='QEMU' and time > now() - 30d group by test_case"
for this query there is a duplicate entry (counted twice, while should be conted once):

"2020-02-13T13:58:28.521930966Z",
"1581596894",
"tests/auto/network/access/qnetworkreply/test",
"ioHttpRedirectPolicy"
],
[
"2020-02-13T13:58:28.521930966Z",
"1581596894",
