I'll make a general comment on this. Let's face it the tube viewers prefer and search for extra length so shorter isn't ideal anymore. Some tubes do a search by length and you will see a noticebable viewer increase from 3 minutes to 5 (both are affiliate standards on most sites). If I had to pick a new standard I would go with 7 minutes and no more ONLY if you aren't giving away the farm. It will put your material above the classic 5 minute default and hopefully earn you more money. Just my 2 cents
