95% of players will never have enough time to get everything in FFXI, if you can only do 1 event a day, it's probably better to accept that fact, and any other event you don't have time to do/gear you can't get just let it go. Or just don't do dyna and do other events.
Although you can only do dyna for 1hr too, but you'd actually farm coins less efficient than doing it for 2hr due to the time spent on TE. I often only do dyna for 1 hour too since I don't have all day, but in reality it's less efficient than staying for 2hr with TEs.
