I agree. There may be a very slight benefit in changing to the slackest setting, this will vary front to back and with top normal and bottom normal dérailleurs. In practice I usually snap a strand at one end or the other before I need to alter the indexing due to stretch. Snapping strands is usually due to friction at the entrance/exit of outers, not tension per se.
