How faction trial reset works?

[Zapherian]

If there is no alts in your faction trial instance after 10 mins, it will reset, its same with all instances

 Exactly what i was trying to learn. Thanx at least now i know i can stay out for 10 minutes. But once i stayed out for like 30 minute and trial didnt reset. Is there anyway to prevent reset?

Put 1 char there, if there is no alt in 10 mins it will reset
