Issue
The maximum value depends on the "Clone Frequency" selected on the clone request
Following is the maximum value as per the clone frequency chosen
-- Monthly - 2
-- Bi-weekly - 3
-- Weekly - 5
However there is currently a discrepancy on the documentation site , where it mentions that maximum value can be "9" , the documentation correction is requested and is currently in progress.
