Actually, I never dared to touch Backpack's reminders because of their "fuzziness". I think that was a very bad idea from the get-go. I would always feel uncomfortable thinking that a reminder could be triggered too late. And from reading and searching through their support pages and the forums, I could never figure out when *exactly* those reminders would be triggered. To add a concrete time (has that always been available and was it only me noticing it too late?), is an additional hassle I don't want to go through every time. IMO, just another case of 37s' dumbing-down things too much.
