Thank you for your reply. You are absolutely right, and I apologize for straying off-topic in this thread. I have moved my thoughts to a separate thread [0].

Unfortunately, cost delay adjustments are off-topic for this thread, as I hinted yesterday [0]. I'd certainly like to explore this idea, but if we can't keep the discussion focused, it'll be hard to get anything committed.
