Dan, you get it! 
And I bet you let the machine spin for about 4 minutes after the initial 1 minute spray and then did another 1 minute spray followed by a 6 minute spin you could skip a deep rinse altogether.
Speaking about 6 minutes there are so many washers that only spin the load for about 4 minutes once the basket comes up to speed. A 6 minute spin after the tub is cruising helps with towels and saves energy in the dryer.
4 minute spin, 1 minute spray, 4 minutes spin, 1 minute spray, 6 minutes spin, = 16 minutes
4 minute fill, 10 minute wash, 16 minute rinse and spin = 30 minutes flat.
Faster than a total deep rinse sequence. Ultra clean clothes in a standard quick wash time.
