Exactly right! Cycling a deep-cycle battery to only 30% discharge rather than 50% discharge on a regular basis can GREATLY extend the number of useful life cycles....as much as 3 times!
That's one of the principal reasons it makes good sense to parallel your batteries into a large battery bank. This larger bank will be drawn down less (smaller percentage) from full charge than would a smaller bank, given the same load.
