Instead of shoe-horning occurrences and timeframe into `if_event()`, what about something like this...

`Notify_Humans()->if_event( 'cloudwatch' )->has_occurrences( 20 )->within_time( "5 minutes" )->then_action( $action );`

`has_occurrences()` and `within_time()` would act upon the `current_recipe`.
