Your dates are significantly off
Wikipedia has a delay listed in a table:

It is, for CentOS-7, For example:

7.0  27
7.1  26
7.2  25
7.3  39
7.4  43
7.5  31
7.6  34
7.7  42
7.8  28


For 6 .. since 6.2, it has bee3n between 10 and 18 days.

For 8:

8.0  140
8.1  71
8.2  48

And EL8 is exponentially harder with an entirely new build system and
the requirement to build modules.
