A test run of FRUEC using only data on 2019-09-20 showed a large discrepancy for Landing Page events and Banner Impressions between legacy and testing databases:
```
MariaDB [(none)]> select count(*) from pgehres.landingpageimpression_raw where timestamp >= '2019-09-20 20:00:00' and timestamp < '2019-09-20 22:00:00';
+----------+

| 2401 |

1 row in set (0.00 sec)
