Bill, Who, me? Paper reviewers are supposed to anonymous. Let's just say I agree with your assessment.
I've seen a number of papers like this; some I have reviewed. They are written by folks with computer science backgrounds and are not well trained in physics and engineering principles and even less in the physical properties of real oscillators. You (and others) might not like the NTP mitigation and discipline algorithms, but each one is based on thorough analysis with respect to sound physics and engineering principles as confirmed by measurement over a wide body of scenarios.
