I would say the TMA is both too perfect in some ways and not perfect enough in others.
Too perfect
- it's pretty quick to get to 95% if you are proactively driving the problem. Not really realistic in that regard most of the time. And in reality, you will never really know if your solution is that good anyway.
- visual contacts are instant 95% solution which is not really true. It takes at least 2-3 observations for even an experienced approach officer.
Not perfect enough
- Drastic changes to solution anytime you lose contact. Existing solution should just extrapolate out.
- There should be at least a best guess for course much earlier. I was trained to always assume something closing until the data says otherwise, especially right after initial gain.
