Gee, I've read this a few times and, even though it's not that clearly explained (and Nate obviously meant "attrition" instead of "contrition), the underlying principles seem sound and compatible to what I think Angie is offering. Tune-up drills can be of varied complexities, depending on the dog, from simple "get in the water" blinds to angles and re-entries. Presuming sound basics on land that have included teaching angle casts on land, both Angie and Nate are proposing casting the dog off of one taught blind to another in the water to teach angles. Angie is further offering what Lardy terms "definitive casting" by handling the dog on the return.
