You must have had at least 3 sessions on every jackday of the jackend in order for it to be considered a true jackend.
If you have one session for every 3 hours of the jackend - you have had an EPIC jackend! this does not mean you must have a session every hours, only that if you divide the total number of hours by 3, you should have had at least that many sessions to be considered and EPIC jackend. For example, 48 hours = 16 sessions, 72 hours = 24 sessions, 96 hours = 32 sessions
Dude 2: "oh man, i haven't hit anything for a month - my balls were smurfed they were so blue. I had a total EPIC jackend, man."
