When comparing data e.g. number of visits, entry pages etc
with data of day before there is a problem:
when checking earlier than 23:59
there is always a difference because
the period taken into account is shorter
than the complete day before
and with this not all "things" of this day has already happened.

An example:
Looking at data at 9:00 in the morning:
actual data is taken from 0:00 to 9:00 = 9h
the data for comparison form 0:00 to 0:00 = 24h

the result looks like this:

=> there are two ways to solve this:

• compare data always the last 24h 9:00-9:00 to the 24h before 9:00-9:00
• compare last full day 0:00-0:00 to the last full day before 0:00-0:00
