Comment (by aidvu):

 Had a long night thought, and I think the
 [https://core.trac.wordpress.org/attachment/ticket/49693/49693-5.patch
 49693-5.patch] is the correct approach for limiting per day.

 The current limit for duplicate recurring events per day is 24
 **DAY_IN_SECONDS / HOUR_IN_SECONDS**, while for longer intervals it is
 **floor( EVENT_INTERVAL / HOUR_IN_SECONDS )**. Duplicate here means:
 **same hook, args, schedule and interval**.

 Tests cover less than day and more than day intervals (although because of
 the longer than day interval one might run for ''>150ms'').
