Trying to figure out how Magento crons are picking the schedules. Read the magento document page and still not satisfied and thought of asking the question here.
I setup the cron as below
Generate Schedules Every : 15 Schedule Ahead for : 20
The cron.php is running for every 10 minutes. The core frequency for email queue is every 1 minute and I havent override that.
When the cron runs, it created too many schedules for core_email_queue_send_all.
Whant to understand why? What is the logic?
