It resets when you go back to the map.

If a card says "raises ATK for 6 turns", then each boost lasts for 6 turns, and yes, even the turns in which the card isn't on the field count. Let's say a card raises ATK by 50% for 6 turns, and you always keep it on a main rotation, never in the third slot.


 * 1st turn: The card super attacks. The SA multiplier gains +50%, but it started with -50% (that's how these cards work, they never do increased damage on their first turn), so no increase here.


 * 2nd turn: Not on the field.


 * 3rd turn: The card gets a +50% ATK boost to its stats, which would benefit a normal attack. If the card super attacks, the stats reset and the boost moves to the SA multiplier instead (if it's 430%, it would go up to 480%).


 * 4th turn: Not on the field.


 * 5th turn: The card gets a +100% ATK boost to its stats, which would benefit a normal attack. If the card super attacks, the stats reset and the boost moves to the SA multiplier instead (it would go up to 530%).


 * 6th turn: Not on the field.


 * 7th turn: The card has now lost the boost from the 1st turn, but if it keeps super attacking, it will keep the +100% boost until the end of the fight.

In other words, "raises ATK for 6 turns" equals to a double boost, while "raises ATK for 3 turns" equals a single boost.
