Well, it's not always a flat time.
My mailer delays a different amount based on the number of attempts.
I try at 0 minutes, 1 minute, 10 minutes, 1 hour, 2 hours, 3 hours,
and every 4 hours thereafter.
But yes, starting the window at 1 minute rarely results in delays
of only 1 minute. At best, it's the minimum delay of the sender,
which as you point out is usually more than 15 minutes,
and has been observed as high as 4 hours in the wild.
