TurboFloat days between and license check

Here is a question. Say a license is issued for a period of 10 months, and the days between setting is 90 days. After 9 months, after the last check by the server, but before the 10 months has lapsed, the customer pays for another 10 months and the license in question is updated. Will the license on the server expire at the end of the tenth month? Will the customer be forced to activate the server manually in order to get the updated activation?Is so, why is the recommended days between setting for TurboFloat 90 days?
