Good find.
I am somewhat concerned with Norfolk's synopsis of premise 7. Rigden does not limit learning to the start of the campaign. He notes the need for continuous reassessment as the campaign continues. As Rigden, rightly, notes, learning is not a "done once and over" process.

A corollary to premise 7, by the way, is that the fact that one does not make mistakes early on does not preclude the possibility of making mistakes as the campaign progesses.
