Is your feature request related to a problem? Please describe.

After analyzing that the actual retention period of an index adds up to the sum of the time until rollover and until phase delete, it results in a standard retention period that is too long. Of course again depending on the volume which decides when an index is rolled over.

Describe the solution you'd like

The delete phase should be slightly decreased for some of the indices to achieve a better standard index lifetime.
