Fall or Spirng? Fertilizer for Winter Wheat

The link in the title is from Westco fertilizer.
Only a few fields of winter wheat were seeded in our area due to dry condtions, but thiscaught my eye.
The page points to yield advantages for fall applied N. I haven't seen this in the field, but I haven't tested it either.
What I have seen is split applications resulting in better yield.(certainly not tested again)
One advantage to putting all or some N down in fall is lower priced N.
Historically fertilizer prices are 10% lower in fall. That can vary and it can invert, but the pattern has been the same in the 25 years I've been in the business.
