I used to think it took a person with exceptional science skills to be successful in this hobby. Now I believe it is a gut feeling when your tank is well or when something needs a bit of attention.I had the pleasure of reading this thread from start to finish (up to last night). Being interested in the consensus, I pulled the information into Excel this morning. The plot below shows the trend in when data was provided, early on in the thread's lifecycle but then petering out over the years and turning into a more philosophical discussion what seemed like fewer members.
More to the point what did the data suggest? Is there a relationship between water change frequency and the age of the set up? Hard to say. If we believe that as tanks matures, water changes aren't as important AND the aquarist relaxes a bit, we might expect to see longer periods between changes as the tank ages. I don't see a trend. There doesn't seem to be a trend between no water changes and age of set up.
What about frequency of water changes and tank size? As you can see, there does not seem to a pattern. One might postulate that bigger set ups would tend to be more stable and not require as frequent water changes as smaller systems.
What about the size of the water change and the size of the system? Again, no trends
While the data did not explicitly give a direction to take, I offer you a potential take away message based on the many arguments that I heard:
1) The frequency and/or the size of water changes will/should decrease as the system matures.
2) Animal and plant growth, and maybe the overall appearance of the tank, should be the guiding principle about water changes, frequency and volume, should or can be altered. Water chemistry tests alone represent an incomplete diagnosis of the system's health.
3) Every system is different and the age of the system alone is an inadequate way to describe its maturity.
4) There is likely to be a lot of implicit knowledge each aquarist possesses about his system that is typically not shared in forums or lectures. Just looking at pictures of aquariums will not lead me to understand why a particular aquarist is so darn successful.
There is probably plenty more to say on this topic, so, I plan on updating the analysis in 2017 or when we double the amount of data.

And that skill can be learned but through years and years of figuring out for yourself what to do.
If your going to improve on that skill then listen to the reefers that had to learn it for themselves
